Rm. Lees et al., ASSIGNMENTS OF FAR-INFRARED LASER LINES IN THE CO-STRETCHING STATE OF0-18 METHANOL, International journal of infrared and millimeter waves, 15(11), 1994, pp. 1883-1906
Far-infrared (FIR) laser and infrared pump transitions of the O-18 iso
topic species of methanol have been assigned for a number of CO2 laser
pump lines with the aid of high-resolution Fourier transform spectra
in the FIR and CO-stretch band regions. The structures of the FIR lase
r energy level systems and the transition assignments were established
through the use of closed transition combination loops, which also yi
eld improved accuracies for the FIR laser wavenumbers.
