    For some singlet or triplet states (during nto calculations), the homo lumo gap for nto's are showing 0 eV, which is not possible. Also, some nto's which should have been n-pi* transitions, are not showing so. Please help me to figure out where I'm going wrong.

    So, .fchk file will also work just like .fch file. Thank you so much Sir for your kind response.

    Hello! Greetings!

    I want to do NTO calculations for which two files are needed i.e., .fch and .out files. I had queries regarding
    1. How to generate .fch file from gaussian? What keyword do we need to add to get the .fch file (like we add 'formcheck' to get .fchk file format)?
    2. Can we use .log file instead of .out file? If not, then how to get .out file?

    Thank you
