Abstract Raman spectroscopy can be used to determine density of gases, because the energy fundamental vibrational modes is affected by intermolecular distances. The key problem estimation exact peak positions bands, analyses require a precision that mostly less than pixel resolution modern spectrometers. A new method bands and atomic emission lines in discontinuous spectrum without numerical ma...
