Flat cells and AquaX cells are available. Spectrometer is equipped with 12” magnet with adjustable poles air gap and 19 kW power supply, providing maximum field strength 1.1T. Variable temperature capabilities from 90K to 370K are performed using nitrogen boil system or nitrogen or oxygen gas with ER 4131VT temperature controller. Spectrometer is equipped with rapid scan and fast digitizer capabilities. Spectrometer is equipped with manual and automatic goniometer for single crystal studies. Spectrometer is linked to local area network and the internet. A Nd:YAG Inlite III-10 high-energy eximer laser (Continuum) is available for flash-photolysis of caged compounds.
