Materials Science & Engineering: ChemDraw / ChemOffice / MNova Lite

ChemOffice, ChemDraw and MNova @ UC San Diego

UC San Diego has a campus-wide license for ChemOffice for Windows, ChemDraw for macOS, MNova Lite (aka MeRestNova Lite ChemDraw Edition), and Signals Notebook Individual Edition. It's funded by the Department of Chemistry & Biochemistry and Campus IT Services. The Library doesn't support these products; this information is just to help you access these resources.

To launch a SciFinder-n or Reaxys search from within ChemDraw: select the structure in question, then select the SciFindern or Reaxys icon. VPN must be running for you to connect to these databases. To add these to your ChemDraw interface, go to Add-ins.

Download and Install ChemOffice (or ChemDraw) and MNova

Start at the Revvity Signals ChemDraw Subscription Gallery and search for the University of California San Diego. You'll see two registration options: the first is for ChemDraw (including MNova), and the second is for the cloud applications.

  • Sign up to create an account with Revvity Signals or log in if you already have an account. Use your email address for registration.
  • From the List Entitlements page, you should get a link or list of available downloads and the product activation code. 
    • From there, you'll get software downloads for ChemDraw Suite v23 Windows, and ChemDraw Professional v23 for Mac OSX, along with the user guides.  
  • To obtain the license ID for MNova, complete the webform on the page or contact with your UC San Diego email address. The ChemDraw order number is also on the List Entitlements page.
  • Please contact maryam at ucsd dot edu if you have problems registering with PerkinElmer or downloading the software. Include something like Revvity Signals registration problem or ChemDraw software installation issue in the subject line.
