Electron Spin Resonance Spectrometer

Bruker

Electron Spin Resonance (ESR), often called Electron Paramagnetic Resonance (EPR), is a branch of spectroscopy in which electromagnetic radiation (usually of microwave frequency) induces transitions between magnetic energy levels of electrons with unpaired spins.

SPECIFICATIONS

ESR spectrometer working at X-band and Q-band with a 10" magnet. For room temperature work special flat cells and an electrochemical cell are available and liquid helium cryostats are included for use with the standard X-band cavity so measurements can be made from 4 K to room temperature.

EXPERIMENTS

• Continuous wave ( CW) ESR
• Pulse- ESR
• Low temperature experiments

SAMPLE REQUIREMENT

The method can be applied to solid and liquid samples.

APPLICATIONS

• Kinetics of radicalic reactions
• Crystal fields in single crystals
• Recombination at low temperature
• Free radicals in living tissues and fluids
• Polymer properties
• Behavior of free radicals in corrosion
• Archaeological dating
• Radiation effects and damage
