A precise measurement of the infrared fundamental bands of HBr79 and HBr81 has been made. The two band centers have been found to be 2,558.94 and 2,558.56 cm-1, respectively. Rotational and vibrational constants have been calculated from the observed

A high resolution Littrow type grating spectrometer designed for four-pass operation in the near ir is described. Using 20-cm gratings, four passed in first and second orders, this instrument achieves a spectral resolution between 0.015 cm(-1) and 0.

The use of low pressures and a high‐resolution spectrometer for the measurement of the absolute line strengths of gases in the near infrared is tested on the first overtone band of carbon monoxide. Measurements are made at pressures from 100 to 500

Explicit expressions for the matrix elements of the dipole moment have been derived for the 1-0, 2-0, and 3-0 vibration-rotation bands of diatomic molecules. The derivation is based on a cubic dipole moment function and on radial wave functions obtai

The line intensities of the five Σ-Σ bands of CO 2 in the 1.43–1.65 μ region have been measured with relatively low sample pressures and high resolution (0.035–0.06 cm −1 ). The data are analyzed to obtain the total band intensities and dipo
