This book is a collection of review papers presented at a meeting held at Squaw Valley, California in the summer of 1964. Most of them are concerned with methods of chemical physics as applied to biological problems. The exception is an excellent article on molecular genetics by F. Gros, entitled "The Cell Machinery." It does not include, however, the recent work on the genetic code by Khorana....

A simple formulation is presented for the analysis of nuclear quadrupole spectra in biaxial liquid crystals based on orientational order parameters. The analysis contains no tilt angle or other model-dependent parameters not directly measured in NMR experiments. The observability and effect of various order parameters on the asymmetry of the electric field gradient q is discussed. It is shown t...
