WebJan 30, 2024 · Introduction. Each of the normal modes of vibration of heteronuclear diatomic molecules in the gas phase also contains closely-spaced (1-10 cm-1 difference) energy states attributable to rotational transitions that accompany the vibrational transitions. A molecule’s rotation can be affected by its vibrational transition because there is a change … WebAug 23, 2011 · How to calculate wavenumber domain coordinates from a 2d FFT.
