 Title    Phase Transformation and Structure of N-chlorocarbonylisocyanide Dichloride  
 Abstract    The 35 C1 nuclear quadrupole resonances in N-chlorocarbonylisocyanide dichloride show that it exists in two polymorphic forms. The metastable a phase has six 3 ~ Cl NQR lines and the stable ß phase has three. The latter is obtained irreversibly by annealing the a phase at 179 K. The temperature depen-dences of the 35 C1 NQR frequencies, spin-lattice and spin-spin relaxation times are obtained in both phases. The results of the 35 C1 NQR studies are discussed together with calculated MNDO level data and other physical properties (IR frequencies, dipole moments) of this compound.
