Abstract
With the advent of semi-conductor lasers and their recent application to spectroscopy (1,2), there has been a revolution in the study of infrared spectra. Use of the tunable diode laser(TDL) has permitted high resolution (<0.0001 CM−1) studies of several molecules of high current interest (C10,HNO3,SO2,CF2C12,etc.). This study is concerned with the experimental determination of the pressure broadened characteristics of a single O3 line near 1129.4 CM−1. This line has been selected by NASA as a possible candidate for remote sensing experiments using either infrared heterodyne spectroscopy or differential lidar, since it is relatively well isolated from other atmospheric lines and has significant strength. A Beer's Law experiment is performed to determine the absorption coefficients and collisional self-broadening parameters.
