Sodium borohydride is a well known reducing agent. In methanol at room temperature formyl and keto groups are readily reduced to alcohol groups, while ester and carboxyl groups, carbon-carbon and… Expand
A PROPOSED STRUCTURE FOR CHLOROPHYLL d
Treatment of chlorophyll a or methyl chlorophyllide a with potassium permanganate effected oxidation of the 2-vinyl group without concomitant oxidation of the cyclopentanone ring. One of the products… Expand
Infra-Red Absorption Spectra of Chlorophylls and Derivatives.
We have measured the infra-red absorption spectra of chlorophyll and some of its derivatives in order to obtain information useful for eventual understanding of reversible transformations of this… Expand

THE ABSORPTION AND REFLECTION SPECTRA OF LEAVES, CHLOROPLAST SUSPENSIONS, AND CHLOROPLAST FRAGMENTS AS MEASURED IN AN ULBRICHT SPHERE
LIGHT‐INDUCED ABSORBANCY CHANGES IN EIMHJELLEN'S RHODOPSEUDOMONAS*
Abstract— Light induced absorbancy changes in Rhodopseudomonas sp. NHTC 133 are analogous to those observed in other photosynthetic bacteria, but all of the features in the light‐induced difference… Expand
