The aim of this study was to verify whether NQR can be the method of identification as to which of the tautomeric forms 1H or 2H of indazole occurs in a given solid-state substance. For this purpose, the enthalpy of formation and parameters characterizing the NQR spectra were calculated and compared

## DichloromethylmethyldiÑuorosilane was synthesized for the Ðrst time. Raman spectra of the (CHCl 2 SiF 2 CH 3 ) liquid were obtained at various temperatures between 298 and 163 K. Spectra of the amorphous solid were recorded at 85 K and spectra of crystalline solids cooled by di †erent technique

## Abstract We describe the conformation and stereospecific ^1^H and ^13^C chemical shift assignments of longifolene 1 and its penultimate precursor 2 through the combined use of __ab initio__ calculations and experimental NMR techniques. The predicted stable conformation for both compounds was sim
