✦ Synopsis

The hyperfine structure of the (J=1 \leftarrow 0) rotational transition of (\mathrm{CuCl}) as well as the (J=) (3 \leftarrow 2,2 \leftarrow 1). and (1 \leftarrow 0) rotational transitions of (\mathrm{CuBr}) in the (v=0) vibrational level have been investigated using a microwave Fourier transform spectrometer. The molecules were produced by laser ablation of the copper halide followed by an axial supersonic expansion into a nearsemiconfocal Fabry-Perot cavity. The analysis of the hyperfine structure yielded improved values of the rotational and electric quadrupole constants and determined the nuclear spin-rotation constants for the first time. The physical implications of these results are discussed. ic) 1993 Academic Press. Inc

## Abstract Solid‐state NMR spectroscopy was applied to the analysis of melanins prepared by peroxidase‐H~2~O~2~ oxidation of dopamines specifically ^13^C labelled in the α‐ or β‐side chain positions. A surprisingly diverse pattern of signals indicated the presence of uncyclized dopamine and noradr
