Abstract
The resonance Raman spectra of dilute cytochrome c and oxyhemoglobin solutions obtained with high peak power (>1 MW) laser excitation at 532.0 nm and optical multichannel analysis (OMA) are presented. The frequencies and intensities of bands in resonance Raman spectra obtained under these conditions are directly comparable to spectra derived from 0.15 W peak power excitation using cw lasers. No anomalous spectral features are observed. These pulsed-laser/OMA spectra are used to comment on the applicability of such techniques for time-resolved resonance Raman spectroscopy of biopolymers.
