摘要：

The infrared spectrum of the ν2 band of nitric acid (HNO 3) has been measured with a tunable diode laser in the frequency interval from 1690 to 1727 cm-1. A total of 430 assigned transitions have been analyzed to yield a set of nine rovibrational constants for the upper state with a standard deviation of 0.0012 cm-1. The band is primarily B type with a band center at 1709.568 ± 0.005 cm-1. Because of the absence of perturbations, the band constants can be used to calculate transition frequencies and relative intensities with a high degree of accuracy.
