Strengths and Collision Broadened Widths in the Second Overtone Band of Hydrogen Fluoride

Abstract

Individual line strengths and self‐broadened half‐widths have been measured in the second overtone band of hydrogen fluoride. The electric dipole matrix element for the band has been determined from the measured strengths. Its value is: $${\text{〈 3|μ(r)|0〉}}_{\exp }{\text{=+1.628× 10}}^{\text{−21}}\hspace{0.17em}\mathrm{esu}·\mathrm{cm.}$$ The m dependence of the measured half‐widths agree with the Anderson theory of collision broadening if off resonant collisions are taken into account.
