  • Using the free trial version
    The free trial version can be obtained on a CD-ROM distributed at various trade shows and academic conferences, or as a download from the JEOL NMR support site (nmrsupport.jeol.com ) Immediately after it is installed, it can be used for a maximum of 15 minutes each time the program is started. To remove the restrictions, a license key is required.
    To obtain a license key you simply register as a user on the JEOL NMR support site and complete the licensing procedure. There is no fee for registration.

Except for this, the contents of the program related to data processing are identical to the purchased version. (※ The free trial version cannot be used to control the spectrometer.)
