Tunable Diode Laser Measurements of Broadening Coefficients of Lines in the nu-6 fundamental of 12ch3d

THE EVALUATION OF PRESSURE BROADENED LINEWIDTHS OF CH3D DESERVES CONSIDERABLE INTEREST FOR THE STUDY OF THIS MOLECULE IN ATMOSPHERIC SPECTRA AND FOR THE POSSIBILITY OF MAKING ESTIMATES OF D/H RATIO IN PLANETARY ATMOSPHERES. N2-, H2- AND SELF-BROADENING COEFFICIENTS OF TRANSITIONS IN THE NU-6 BAND OF 12#CH3#D AT ABOUT 9.2 MUM HAVE BEEN MEASURED USING TUNABLE DIODE LASER SPECTROMETRY. THE DATA ARE ESTIMATED ACCURATE WITHIN PLUS/MINUS 5 PERCENT. A COMPARISON OF THE OBTAINED VALUES WITH THOSE PREDICTED BY THE EXISTING THEORY SHOWS A DISCREPANCY FAR IN EXCESS OF THE UNCERTAINTY OF THE EXPERIMENTAL MEASUREMENT FOR H2-, N2- AND SELF-BROADENING.
