Pulsed and continuous-wave electron paramagnetic resonance Bruker EleXsys 500-E EPR Spectrometer is equipped for continuous wave X-band spectroscopy, a light-accessible cavity, and accommodates variable temperatures. The magnetic field operates at up to 1.5 Tesla. VT X-BAND PULSED ELECTRON PARAMAGNETIC RESONANCE (EPR) WITH LIGHT EXCITATION CAPABILITY. Pulsed EPR techniques enable controllable manipulation of electron spins and spin dynamics in the nanosecond time regime. With a wide variety of pulse sequences, the Bruker ELEXSYS-II 580 X-band EPR spectrometer allows one to ascertain extensive knowledge about structural properties surrounding probed spins as well as their mutual interactions. Coupled with light excitation, pulsed EPR gives unprecedented control of the excited states, their spin populations, and the mechanisms of their interaction with the environment. This variable temperature system provides detection resolution of 1 nanosecond and excitation and detection of signals up to 1 GHz. This allows for the study of quantum phenomena in crystalline and optically active media. Operational modes include: ESSED: Echo Saturation and Stimulated Echo Decay ESEEM: Electron Spin Echo and Envelope Modulation HYSCORE: Hyperfine Sub-level Correlation Spectroscopy ENDOR: Electron Nuclear Double Resonance DEER/PELDOR: Double Electron-Electron Resonance/Pulsed Electron Double Resonance SECSY: Spin Echo Correlation Spectroscopy EXSY: Exchange Spectroscopy
