Abstract
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.
