Comments: The curve of toxicarol shows a maximum at 274.1 nm with a molecular extinction coefficient 23000. The curve drops down 
vertically at a wavelength 280.1 nm covering an extinction range from 19000 to 24000. The absorption curve of dehydrotoxicarol has 
two maxima, one being at 278.0 nm with molecular extinction coefficient 20250, the other at 330.4 nm with molecular extinction 
coefficient 7180. One minimum occurs at 311.4 with coefficient at 5320.
