Vibrational spectroscopic study of terbutaline hemisulphateAli, H.R.H., Edwards, Howell G.M., Kendrick, John, Scowen, Ian J. 01 May 2009 (has links)
No / The Raman spectrum of terbutaline hemisulphate is reported for the first time, and molecular assignments are proposed on the basis of ab initio BLYP DFT calculations with a 6-31G* basis set and vibrational frequencies predicted within the quasi-harmonic approximation; these predictions compare favourably with the observed vibrational spectra. Comparison with previously published infrared data explains several spectral features. The results from this study provide data that can be used for the preparative process monitoring of terbutaline hemisulphate, an important ß2 agonist drug in various dosage forms and its interaction with excipients and other components.

Vibrational spectroscopic study of salbutamol hemisulphateAli, H.R.H., Edwards, Howell G.M., Kendrick, John, Scowen, Ian J. 01 January 2009 (has links)
No / Salbutamol hemisulphate is a relatively selective ß2-adrenergic agonist and is used as a bronchodilator. In this work, we present a detailed vibrational spectroscopic investigation of salbutamol hemisulphate using mid-infrared and near-infrared Fourier-transform (NIR-FT) Raman spectroscopies. These data are supported by quantum chemical calculations, which allow us to characterise the vibrational spectra of this compound reasonably. As such, this study could be viable for examining the way in which this drug interacts with its target molecules.
