How do I access PSDS resources?

To access the CSD Remote Desktop, please send us a request for a CSD Remote Desktop username and password. This username and password can then be used to access the CSD Remote Desktop from any location.

All other services are accessed via web interfaces, and should automatically be accessible to users on UK academic networks. (When accessing the CSD or CrystalWorks, you will first be asked to accept the relevant terms and conditions of use.) If you encounter a login screen while on your institution’s network, please let us know.

If you require access to web-based services from outside your institution, please go to the registration page to a request a PSDS username and password. The PSDS also now supports login via Shibboleth on our log in page, if you already have a PSDS user account you will be able to merge this with your shibboleth login.

If you are experiencing difficulties accessing PSDS services, please send us an email and we’ll get back to you as soon as possible.

Resources currently available via the PSDS

The Physical Sciences Data-science Service currently offers access to the following resources under a general UK academic licence.

  • ACD/I-Lab

    ACD/I-Lab is an online tool which features predictions and databases of physical-chemical properties and NMR spectral information.

  • Cambridge Structural Database (CSD)

    The Cambridge Structural Database (CSD) is a collection of over 600,000 small-molecule organic and organometallic crystal structures that can be visualised and downloaded.

  • CrystalWorks

    CrystalWorks is developed by the Science and Technology Facilities Council (STFC) at Daresbury, and provides access to the wide range of crystallographic structural data made available by the Physical Science Data-science Service.


    DETHERM is one of the world’s largest thermophysical databases.

  • Inorganic Crystal Structure Database (ICSD)

    The Inorganic Crystal Structure Database (ICSD) is a database provided by FIZ Karlsruhe GmbH.

  • Chemical Availability Search

    Find a supplier for your chemical through this PSDS portal, searching the directories of many suppliers to source your chemicals. 

  • MNova Spectroscopy Software Trial

    Join our 12-week evaluation trial of the powerful spectroscopy software from Mestrelab Research. This offers capabilities in NMR, MS, UV/Vis and many more spectroscopy techniques as well as powerful tools for analysing, visualising and reporting spectroscopy data.


Data Services not currently supported by PSDS

The predecessor service to the PSDS, the Chemical Data Service, provided access to some data services that are no longer linked directly via the PSDS proxy. This is because these services are now freely available to UK Academic users and can be accessed directly without needing to go through PSDS. We provide links to these here for convenience:

  • Chemicalize

    Chemicalize is a public web resource which identifies chemical structures in webpages and other text using ChemAxon's Name to Structure parsing. To access Chemicalize, you will need to register with the Chemicalize service.

  • ChemSpider

    Chemspider is a free chemical structure database providing access (as of June 2019) to over 73 million structures, properties and associated information from more than 400 data sources.
