electron spin resonance (ESR)

 or electron paramagnetic resonance (EPR)

Technique of spectroscopic analysis (see spectroscopy) used to identify paramagnetic substances (see paramagnetism) and investigate the nature of the bonding within molecules by identifying unpaired electrons and their interaction with their immediate surroundings. Unpaired electrons, because of their spin, behave like tiny magnets and can be lined up in an applied magnetic field; energy applied by alternating microwave radiation is absorbed when its frequency coincides with that of precession of the electron magnets in the sample. The graph or spectrum of radiation absorbed as the field changes gives information valuable in chemistry, biology, and medicine.

ESR Technology recruits oil, gas safety expert ESR Technology, one of the industry's leading engineering, safety and risk management consultancies, today announced the appointment of Martyn Foote as general manager of its Aberdeen operation.
These low-carbon steels are said to have low residual stresses, which helps achieve nearly distortion-free machining, and their high cleanliness (claimed to be close to ESR levels) facilitates polishing and etching.
Several Gulf Cooperation Council countries have shown interest in nuclear energy -- including Kuwait and Qatar -- but it is in the United Arab Emirates where moves to establish a legal and regulatory framework for the new industry are at an advanced stage with firm decisions expected any time now," said Pat Lawless, CEO of ESR Technology, a company with operational bases in the UK and the Middle East.
