Abstract
The continued development of CARS as a combustion research tool calls for increasingly accurate knowledge of spectroscopic parameters such as Raman linewidths, line shapes, and transition frequencies and nonresonant electronic susceptibilities of combustion species. High-resolution inverse Raman spectroscopy (IRS) has been invaluable in providing Raman linewidths1,2 for N2 and CO as well as accurate molecular constants. However, this technique has limited sensitivity for in situ investigations and does not provide nonresonant susceptibilities. While similar high-resolution CARS systems have been used for general spectroscopy,3 we know of no applications of such systems to combustion environments.
