✦ Synopsis

The ν 2 fundamental bands of 79 BrNO 2 and 81 BrNO 2 , located around 787 cm -1 (12.7 µm), were recorded using a highresolution Fourier-transform infrared spectrometer. A total of nearly 5000 transitions with J ≤ 80 and K a ≤ 30 were reproduced using a Watson-type A-reduced Hamiltonian with a root-mean-square deviation of better than 5 × 10 -4 cm -1 . Rotational and centrifugal distortion constants for the v 2 states have been determined, as well as an improved set of ground state constants for both isotopomers. Due to their sharp Q branches falling into an atmospheric "window," the detection of the ν 2 bands might be an advantageous route for future attempts to detect atmospheric BrNO 2 .

Absolute line intensities were measured at high resolution with a tunable diode laser. This work concerns the 2 2 0 band of cyanogen chloride ClCN in the region 780 cm Ϫ1 . Thirty-two absorption lines were recorded for the isotopomer 35 ClCN and 26 lines for 37 ClCN. From the analysis of these lines

A strong absorption band at 3590 +/- 20 cm-1 (2.790 +/- 0.015 micrometers) has been discovered in the spectrum of Io using the Kuiper Airborne Observatory (KAO). The 2 nu1 + nu3 combination mode of solid SO2 falls at this position. Since SO2 is abundant on Io it must contribute to the new band. Howe

In this paper we investigate the mid-infrared spectrum of the H 2 16 O molecule between 3367 and 3447 cm -1 to study the gas-collision-broadened linewidths. The coherent radiation used in this experiment is produced through difference frequency generation in a periodically poled lithium niobate crys
