β¦ Synopsis
Ab initio calculations including M011er-Plesset second order perturbation (MP2), density functional theory (DFT), complete active space self-consistent field (CASSCF) and multireference singles and doubles configuration interaction (MRSDCI) computations are carried out for the YIrC and YC:Ir molecules. Several alternative structures are optimized and the vibrational frequencies are computed. Thermodynamic properties such as the Gibbs energy functions and heat content functions are computed and compared with the available experimental data. The nature of chemical bonding in these molecules is analyzed.

## Abstract Single crystals of 5β(4βchlorophenyl)β2,2βdimethylβ3β(1,2,4βtriazolβ1βylmethyl)βpentomβ3βol (tebuconazole) were obtained in toluene. The singleβcrystal Xβray diffraction studies showed that it crystallized in the monoclinic system, with space group __P__2(1)__/c__ and crystal parameter
