A computer aided system for research on the quantitative laser spectroscopy of ethylene

Spectral line strength, self- and N2-broadened widths of 282,27–281,27 transition of ethylene v7 band have been obtained at room temperature and were agree well with the results of theoritical calculation. With those spectral parameters, the temperature dependence of C2H4 absorption coefficients at CO2laser transition 10P(14)were measured. The results showed that the temperature dependence of the linewidth was close to T−0.4. A computer aided system was used so that the accuracy of the measurement was well improved than that we did before.
