Hypersensitization by baking of certain Kodak photographic prates for use in high-resolution Raman spectroscopy.
Hypersensitization by baking of various Kodak photographic emulsions is studied from the point of view of high-resolution Raman spectroscopy. In the 4400-4900-A region baking can increase the sensitivity of IIa-O plates to ~4 times that of 103a-O plates for long exposures. In the Raman region for Ar(+) laser excitation, 4700-5800 A, baked Ila-D plates show good sensitivity and low reciprocity failure. Baked IIIa-J plates have better resolving power than the IIa-D type, but the reciprocity failure is greater, and the useful region does not extend beyond 5300 A.
