Abstract

We have applied photoacoustic detection to the observation of the weak visible overtone transitions of CH₄ and NH₃. Spectra were obtained by placing the photoacoustic cell in the cavity of a dye laser and scanning the laser across the absorption band. A spectral resolving power of over 200 000 proved to be adequate to resolve single rotational features (probably rotational manifolds) within these complex bands. The application of these results to the observational study of the major planetary atmosphere is indicated.
