Stabilization Technique

The high resolution spectrum of the 2 υ9 band of HNO3 has been recorded by a tunable diode laser spectrometer with a newly developed frequency stabilization technique. The spectral data were digitally stored and processed by a dedicated micro-computer in order to improve the sensitivity and the precision of the measurements. In addition to the anomalies due to the Fermi resonance with the υ5 = 1 state, we have observed the line doubling caused by the internal rotation of the OH group.

The absorption spectra of carrier free 14C16O2 in the spectral range of 2290-2150 cm−1 by a medium resolution FTIR spectrometer, and the spectral region of 2258 − 2229 cm−1 with a high resolution tunable diode laser spectrometer have been recorded. Spectroscopic constants were calculated from the 0001 − 0000 and 0111 −0110 transitions.
