Investigation of the mechanical vibrations excited by multiple light sources in a protein.

Understanding of physical properties of proteins remains a vital area of research. Many experiments show that light can significantly affect protein folding processes. We attempt to IR and Raman spectroscopy to observe the changes in protein structure of egg white brought on by the illumination by a HeNe laser. Raman spectroscopy has previously been used to detect THz mechanical vibration in lysozymes. We may be producing THz vibrations in the ovalbumins (egg white proteins with molecular weight 42.7 kDa which denature at 84 C.)
