摘要: Homogeneous linewidths of single rotational lines have been measured in the ‘‘channel three’’ region C6H6. The necessary spectral resolution about 5 MHz and high sensitivity were achieved by Doppler‐free two‐photon spectroscopy within an external cavity setup. Linewidths produced intramolecular relaxation found to increase strongly with increasing J for K=0 constant vibrational energy Eexcess =3412 cm−1. This result together investigated structure highly resolved spectrum 1410120 band is a strong indication that Coriolis coupling plays important role redistribution process.
