have been irradiated in the isotropic, smectic B, and two solidphases of n-butyl stearate (BS). The lengths of the ketones were varied from 11 to 31 carbons. The ratios of elimination/cyclization products and diastereomeric cyclobutanol products were measured for each as a function of temperature and BS phase. The effect of 1 and 2 on the phase transition temperatures of BS has been correlated with changes
