Determination of atmospheric carbon dioxide concentration using Raman …
2018年6月1日 · The paper demonstrates the possibility of measuring the carbon dioxide (CO 2) concentration in atmospheric air using Raman spectroscopy. Three methods have been studied for deriving the CO 2 concentration from the Raman spectra (the peak intensity ratio, the integrated intensity ratio, the contour fit method).
