This page applies to all Gaussian versions running on all UNIX-based operating systems. The current products are Gaussian 16 and Gaussian 16M (single system Mac OS X version); some earlier Gaussian versions also had a Gaussian nnIM variant.
Section 1194.21

The above are the only sections applicable to this software.
The software is not web-based, so Section 1194.22 does not apply.
Section 1194.21 Software Applications and Operating Systems – Detail
Voluntary Product Accessibility Template
| Criteria | Supporting Features | Remarks and Explanations |
| (a) When software is designed to run on a system that has a keyboard, product functions shall be executable from a keyboard where the function itself or the result of performing a function can be discerned textually. | Supports | Gaussian is run via a command line interface. |
| (b) Applications shall not disrupt or disable activated features of other products that are identified as accessibility features, where those features are developed and documented according to industry standards. Applications also shall not disrupt or disable activated features of any operating system that are identified as accessibility features where the application programming interface for those accessibility features has been documented by the manufacturer of the operating system and is available to the product developer. | Supports | Gaussian has no effect on any operating system features. |
| (c) A well-defined on-screen indication of the current focus shall be provided that moves among interactive interface elements as the input focus changes. The focus shall be programmatically exposed so that Assistive Technology can track focus and focus changes. | Not Applicable | The software does not have a graphical user interface. |
| (d) Sufficient information about a user interface element including the identity, operation and state of the element shall be available to Assistive Technology. When an image represents a program element, the information conveyed by the image must also be available in text. | Not Applicable | The software does not have a graphical user interface. |
| (e) When bitmap images are used to identify controls, status indicators, or other programmatic elements, the meaning assigned to those images shall be consistent throughout an application’s performance. | Not Applicable | The software does not have a graphical user interface. |
| (f) Textual information shall be provided through operating system functions for displaying text. The minimum information that shall be made available is text content, text input caret location, and text attributes. | Supports | The software output is plain text, which is displayed using standard OS functions. |
| (g) Applications shall not override user selected contrast and color selections and other individual display attributes. | Supports | Contrast and color selections are accomplished through normal operating system controls. Gaussian will not override any user selectable settings or customization. |
| (h) When animation is displayed, the information shall be displayable in at least one non-animated presentation mode at the option of the user. | Not Applicable | There is no animation in Gaussian. |
| (i) Color coding shall not be used as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. | Not Applicable | The software does not have a graphical user interface. |
| (j) When a product permits a user to adjust color and contrast settings, a variety of color selections capable of producing a range of contrast levels shall be provided. | Supports | Contrast and color selections are accomplished through normal operating system controls. Gaussian will not override any user selectable settings or customization. |
| (k) Software shall not use flashing or blinking text, objects, or other elements having a flash or blink frequency greater than 2 Hz and lower than 55 Hz. | Supports | The software does not display any flashing or blinking text. |
| (l) When electronic forms are used, the form shall allow people using Assistive Technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. | Not Applicable | No forms are used in the software. |
Section 1194.31 Functional Performance Criteria – Detail
Voluntary Product Accessibility Template
| Criteria | Supporting Features | Remarks and Explanations |
| (a) At least one mode of operation and information retrieval that does not require user vision shall be provided, or support for Assistive Technology used by people who are blind or visually impaired shall be provided. | Supports | Text to Speech assistive technologies supported by the operating system can be used with Gaussian. |
| (b) At least one mode of operation and information retrieval that does not require visual acuity greater than 20/70 shall be provided in audio and enlarged print output working together or independently, or support for Assistive Technology used by people who are visually impaired shall be provided. | Supports | Text enlarger software that works with the operating system will work with Gaussian. |
| (c) At least one mode of operation and information retrieval that does not require user hearing shall be provided, or support for Assistive Technology used by people who are deaf or hard of hearing shall be provided. | Not Applicable | No audio. |
| (d) Where audio information is important for the use of a product, at least one mode of operation and information retrieval shall be provided in an enhanced auditory fashion, or support for assistive hearing devices shall be provided. | Not Applicable | No audio. |
| (e) At least one mode of operation and information retrieval that does not require user speech shall be provided, or support for Assistive Technology used by people with disabilities shall be provided. | Not Applicable | No speech. |
| (f) At least one mode of operation and information retrieval that does not require fine motor control or simultaneous actions and that is operable with limited reach and strength shall be provided. | Supports | Standard Assistive Technologies that work with the operating system will allow users to use Gaussian. |
Section 1194.41 Information, Documentation and Support – Detail
Voluntary Product Accessibility Template
| Criteria | Supporting Features | Remarks and Explanations |
| (a) Product support documentation provided to end-users shall be made available in alternate formats upon request, at no additional charge. | Supports | Help documentation for Gaussian is available as printed documentation, and on our website in HTML and/or PDF format. |
| (b) End-users shall have access to a description of the accessibility and compatibility features of products in alternate formats or alternate methods upon request, at no additional charge. | Supports | Information on the accessibility and compatibility features of Gaussian products is available here. |
| (c) Support services for products shall accommodate the communication needs of end-users with disabilities. | Supports | Support is provided by electronic mail. Users can utilize a mailer program which provides the accessibility features they require. |
