Abstract:

We record the absorption spectrum of the HD16O molecule in the visible region near 0.59 mm using an acoustooptical spectrometer based on a dye laser. The two important features of this experiment were that the acoustooptical detectors were located within the laser cavity and that the laser was operated in two-frequency mode; this leads to a substantial increase in spectrometer sensitivity and an improvement in the controllability and stability of the laser. We carried out an assignment of the lines in the spectrum, determined the rotational and vibrational energy levels for the (005) state, measured the location of the band center, and determined the rotational constants as well as the centrifugal-distortion coefficients.
