Abstract:

A method of sensitivity calibration of multichannel Raman spectrometers is described which employs the fluorescence spectrum of quinine as an intensity standard. The reported absolute fluorescence spectrum of quinine was least-squares fitted with a polynomial so that it gave an interpolation of the spectrum in the "Raman scale." The obtained least-squares-fitted fluorescence spectrum was cross-checked with the rotational Raman spectrum of D₂. The fluorescence intensities calculated for every 100 cm⁻¹ from the two Ar⁺ laser lines are tabulated for convenience.
