Question

how does changing the bandwidth affect the spectrum of the benzene vapor

Answer 1

Answer:

If the slit width is increased so that the spectral bandpass equals the absorption peak width, the photon SNR increases by a factor of 9 and the detector SNR increases by a factor of 140, but in that case, the analytical curve is sufficiently non-linear that the average concentration prediction error is as much as 3%.
