The effects of exchange and electron-electron dipolar interactions on electron spin echo envelope modulation and free induction decay in a photo-induced spin-correlated radical pair are examined. Analytical expressions are derived for FID and spin echo signals as a two-dimensional function of the ti
## Abstract Electron Spin Echo Envelope Modulation (ESEEM) data are reported for three gadolinium (III) chelates, GdβEDTA, GdβDTPA, and GdβTTHA, in frozen D~2~O/CH~3~OD glasses. This series includes GdβDTPA, an MRI contrast agent that is in clinical use. Threeβpulse electron spin echo modulation pa
Electron spin echo envelope modulation (ESEEM) has been stud- imposed (3, 4). Since commercial pulsed EPR spectromeied at zero and low magnetic fields (B Β°100 G) by means of ters normally operate at X-band frequencies (8-10 GHz), optically detected magnetic resonance. Qualitative differences of the
