A new experimental technique for the study of
atom-surface interactions is obtained by passing an atomic
beam containing high-Rydberg states through a fine mesh
target. The technique is demonstrated to be a sensitive
probe of the electric fields of adsorbed dipole layers in
transmission experiments in which a time-dependent beam...
A novel acyl protecting group for cytosine and adenine has been prepared
from 4-( chloromethyl) benzoic acid. Reaction of the acid with morpholine produces
4-( 4-morpholinyl )methyl benzoic acid which is converted to it's acid chloride
with thionyl chloride. This may be used to acylate cytidine and adenosine under
standard...
