I used it to obtain the vibrational frequencies of a molecule (C39H41PS2) containing one phosphorus carbon double bond by using the keyword "freq". I used Molden to visualize the calculated IR Spectrum. Since there are a lot of frequencies and the phosphorus carbon double bond may have a low intensity, I am having a hard time finding its frequency on the "Molden Frequency Select" panel. I wonder if there is any way to obtain this information in other ways, such as from the text output file, and if there is, how can I do it? Thank you very much. Sincerely, Daniel Morales Salazar
