General description

Cyclohexane-d12, a deuterated cyclohexane, is a standard purity solvent useful for routine NMR (Nuclear Magnetic Resonance) studies. Its infrared (vapor and liquid phase in the range of 376-4000cm-1) and Raman (liquid phase) spectral investigations have been reported. Ring inversion of cyclohexane-d12 has been studied by recording its deuterium NMR spectrum in the temperature range -36 to +115°C. It can be prepared by reacting benzene-d6 and deuterium.
