Exchange interactions and relaxation in paramagnets
Thesis
Beswick, J. Exchange interactions and relaxation in paramagnets. https://keele-repository.worktribe.com/output/412863

This thesis presents some investigations into a variety of paramagnetic systems. Electron paramagnetic resonance is often used to investigate the behaviour of paramagnetic ions present as substitutional impurities in diamagnetic host crystals. Measur...

Some studies of vibrational relaxation using a shock tube
Thesis
Gutteridge, R. Some studies of vibrational relaxation using a shock tube. https://keele-repository.worktribe.com/output/412913

The vibrational relaxation of HCl, HBr, HI or DCl has been studied either as a pure gas or in mixtures with argon, nitrogen or carbon monoxide. Infrared radiation from the second or third vibrational levels was used to follow the relaxation process.... Read More about Some studies of vibrational relaxation using a shock tube.

Studies of the reactions of 3H-pyrrolizines with acetylenes
Thesis
Johnson, D. Studies of the reactions of 3H-pyrrolizines with acetylenes. https://keele-repository.worktribe.com/output/412921

An attempt was made to synthesise azonia-azulenium salts by the 2+2 cycloaddition of acetylenes to 3H-pyrrolizine, and the subsequent ring expansion of the cyclobutene product.
In Part I the attempted syntheses of some new 3Hpyrrolizines are describ... Read More about Studies of the reactions of 3H-pyrrolizines with acetylenes.

Gas incorporation in sputtered and evaporated metal films
Thesis
Mitchell, I. V. Gas incorporation in sputtered and evaporated metal films. https://keele-repository.worktribe.com/output/412924

The argon and nitrogen gas concentrations in thin films have been measured for seven different metals. Sputtered and evaporated films are deposited on glass and tungsten substrates in a stainless steel ultra high vacuum system, which is designed to o...

Studies on the structure of the insect feeding inhibitor azadirachtin
Thesis
Percy, G. Studies on the structure of the insect feeding inhibitor azadirachtin. https://keele-repository.worktribe.com/output/412925

Azadirachtin C35H44O16, a locust feeding inhibitor, was first extracted from neem seeds by Butterworth in 1967. Butterworth identified two acetate esters, two carboxymethyl groups, a tiglate ester, two hydroxyl groups and a 2,3-dihydrofuran ring in t...

Electrostatic space focusing of molecular beams: some methods and applications
Thesis
Sweeting, R. C. Electrostatic space focusing of molecular beams: some methods and applications. https://keele-repository.worktribe.com/output/412926

Electrostatic space focusing of molecular beams has been introduced by means of a brief review of some methods which have been employed in the development of microwave spectroscopy of molecules.
Some electrostatic focuser configurations suitable for... Read More about Electrostatic space focusing of molecular beams: some methods and applications.
