Using synchrotron radiation as a light source, absorption spectra of membrane lipids and spike proteins, viral components of Sendai virus, were obtained in the wavelength regions from 130nm to 320nm. The absorption spectrum of lipids have a broad peak at 190nm and a steep rise below 160nm, while purification of lipids caused a decrease in absorption at the wavelength longer than 170nm and an increase below 160nm. From this result, the rather flat absorption of crude lipids in the longer wavelength region is concluded to originate from diffused reflection. Spike proteins show a small peak at 280nm and a shoulder at 230nm in addition to a more pronounced peak at 190nm and a slight increase below 160nm. They give more diffused reflection of light than lipids. This is ascribed to the fact that they have no better solvent to transform themselves into thin films.
