SUMMARY OR ABSTRACT
Text of Note
Over the past couple of decades, the study of infrared spectra of carbon monoxide has been the subject of interest because of its existence in the Earth's atmosphere as well in different planetary atmospheres. This work presents a line-shape study transitions of pure carbon monoxide and carbon monoxide mixed with air in the fundamental band, recorded over a temperature range from 79 K to 296 K using a high-resolution Fourier Transform Spectrometer (FTS). In this study, different pressure induced line-shape parameters as well as their temperature dependences have been measured and compared with relevant previous published results. Also, the transformation of line-shapes due to line-mixing and Dicke narrowing effects have been investigated. Two semi-empirical approaches, namely: the Exponential Power Gap (EPG) and Energy Corrected Sudden (ECS) approximation have been employed for theoretical calculation of line-mixing coefficients which show good agreement with the measured values.
