Measurement of CO Q-branch Raman Spectrum by using High Resolution Inverse Raman Spectrometer

고분해능 Inverse 라만 분광기를 이용한 CO Q-branch 라만 분광 측정

Raman vibrational Q0branch spectra of pure CO are measured by using the technique of quasicw inverse Raman spectroscopy utilizing a pulsed single-frequency laser source. This approach gives enhanced sensitivity compared to earlier work which employed CW lasers, allowing extension of that work to higher accuracy, higher J states, and higher pressure. Fitting laws with pertubation theory and modified energy gap(MEG) theory are described, and the line broadening and shifting coefficients of J=0 to 24 are determined with both fitting laws.
