N2 - A simple method for isolation of a band from a complicated vibrational spectra without making any preliminary assumption about its shape is proposed. It uses difference spectra between the spectra of naturally abundant and isotopically substituted samples as input, and is feasible when the isotopic shift is significantly smaller than the bandwidth. The limitations and precision of this method are studied. The effect of a noise on the isolation quality is estimated. The developed procedure is successfully used to isolate a resonance Raman band, which corresponds to the iron-histidine vibration of sperm whale deoxymyoglobin.
