Abstract

The reversible abstraction of hydrogen from benzene‐1,3,5‐triol by photoexcited α‐tetralone or α‐indanone in solutions of methanol leads to CIDNP in the ^13^C NMR spectra of these compounds. The information gained from the phase of the polarization in the CIDNP spectra is used to resolve the ambiguities in the assignment of the ^13^C NMR lines for α‐indanone and α‐tetralone, arising from conflicting literature data. Chemical shifts for both compounds in methanol are reported. 2′‐Methylacetophenone does not exhibit CIDNP in the ^13^C spectrum under similar conditions.

Melittin is a naturally occurring hexacosa peptide which forms an amphiphilic helix in methanol, a random coil in water, and a tetramer of helices at basic pH or in the presence of a high salt concentration. The monomeric structure in methanol has been well characterized by proton NMR (Pastore et al
