Two-dimensional Exchange 35Cl NQR Spectroscopy of Chloral Hydrate

Two-dimensional Exchange Spectroscopy Using Pure NQR*

Exchange between positions with different resonance frequencies can be studied by two-dimensional spectroscopy originally developed for the NMR case. Cross intensity reflects changes of the resonance frequency due to different line shifts or anisotropic interactions. We now present analogous experiments carried out with pure NQR of polycrystalline samples. The specific requirements are discusse...

Chloral and Chloral Hydrate

These substances were considered by a previous Working Group, in February 1995 (IARC, 1995). Since that time, new data have become available and these have been incorporated into the monograph and taken into consideration in the present evaluation.

Chloral and Chloral Hydrate

Chloral hydrate

Major uses Chloral hydrate (synthesized in 1832 and introduced into medicine 1869) is the oldest member of sedative-hypnotic drugs. To the same group belong paraldehyde, bromide, urethane, and sulfonal. Metabolite of chloral hydrate, trichloroethanol, is also an excellent hypnotic agent, but is not often used as such due to its physical and irritant properties. At present, chloral hydrate is la...
