Abstract: The analysis of experimental configurations is the foundation for quantitative analysis in sum frequency generation vibrational spectroscopy (SFG-VS). The incident angles affect the signal intensity of some modes of vibration and the detection efficiency of the SFG signal. However, the issue of detection efficiency has not been included in previous experimental configuration analysis studies. According to the principle of the conservation of energy and momentum in coherent optics we simulated and analyzed the effect of incident angles, frequency of the incident light, and other factors on the output signal angle of difference frequency generation vibrational spectroscopy (DFG-VS) and SFG-VS. We intended to determine the reasonable and effective experimental configurations with more combinations of incident angles and less dispersion of the signal output angle. We found that SFG-VS with the co-propagation experimental configuration and DFG-VS with the counter-propagation experimental configuration favour the collection of the signal and quantitave analysis of the SFG-VS and DFG-VS.
