Abstract

Abstract It has been found that ultrasound could accelerate the synthesis of piperidine and piperazine N-oxyl radicals. These radicals were investigated for their utilization as spin probes for checking the properties of liquid crystals. Electron impact mass spectra of the N- oxyl radicals were recorded and their fundamental fragmentation pattern was proposed.
