CURRENT PULSES IN BETA-CAROTENE.

摘要: WE are at present investigating the absorption spectra and photoconduction behaviour, as well electric properties of polyene molecules, in particular, molecule β-carotene. This occurs widely plants animals. Although β-carotene itself does not occur visual pigments it can be considered a precursor retinene, C20 carotenoid, which rods cones retina. An attractive feature this to us was possibility growing single crystals making our electrical spectroscopic measurements along different crystal directions. We have been able make extremely thin (∼ 500 A thick), much larger crystals, we shall reporting full account work elsewhere1. Here wish point out an interesting phenomenon observed during measurements.
