The methods involved, which are comparatively new, are described, and the relative advantages and disadvantages of tunable laser versus synchrotron radiation sources are explained. Examples of recent spectra are then given, drawn from our program at Imperial College, and this is followed by some ...
Throughout the development of dissolution testing, a natural bond has been established between dissolution and spectroscopy. Dissolution testing is especially reliant on UV spectroscopy for detecting the amount of drug released in the medium. In tradi...

Finally, the benefits and drawbacks of a number of chemical techniques (in particular electron spin resonance (ESR), Fourier transform infrared spectroscopy (FTIR), hydroperoxide determination and chemiluminescence), which in principal could provide durability information in a fraction of the time of ...
The first example of a uracil covalently bound to cysteine was reported by Smith and Aplin [23] using NMR spectroscopy and mass spectrometry (Fig. 2A) resulting in formation of 5-S-cysteine-6-hydrouracil. Since then, many more combinations of amino acid/nucleobase cross-links have been ...
