Abstract
A newly designed multichannel Fourier transform infrared spectrometer has been constructed for single-event time-resolved spectroscopy. It i s capable of measuring unrepeatable transient events such as phase tra nsitions, explosions, etc., with a time resolution of up to 5.14 ms. T he mid-infrared region of 4500-2500 cm(-1) is covered with a maximum s pectral resolution of 13 cm(-1). The developed system is used to measu re the phase transitions of alkanes. The solid-solid and solid-liquid phase transitions of octadecane and nonadecane have been studied with time resolutions of 5-50 ms.
