Abstract
Absolute line strengths and self broadened half widths in the second overtone band of hydrogen fluoride have been measured using a high resolution 3 meter Ebert spectrometer with an average spectral resolution of $0.07 cm^{-1}$. The matrix elements of the individual lines have been determined, and their J dependence has been compared with the theory of Herman, and $Wallis^{1}$ and with numerical computations using a Morse potential and a dipole moment function emperically determined from fundamental and first and second overtone band intensity measurements. The observed half widths are in agreement with the Anderson $theory^{2}$, except that an anomalous non-linear dependence of half width on pressure has been observed for some of the lines.
