Optically detected magnetic resonance apparatus

Optically-detected magnetic resonance spectroscopy (ODMR) has been used to study the chlorophyll triplet state. Clarke et al.40) utilized an apparatus combining a pair of argon lasers with a microwave spectrometer. Preliminary results are dedicated to determinate structural dynamical features of chlorophyll in vivo. In such experiments the chlorophyll triplet state can be considered as a paramagnetic probe for the surroundings and interactions within the photosynthetic systems40. ... [Pg.31]

PLE) spectra. Optically detected magnetic resonance (ODMR), a variant of the PL technique, is also a very effective method, especially in identifying the nature of the defects involved. A typical PL apparatus is shown in Figure 3.1 and is composed of a light source for excitation (typically a He-Cd laser for ZnO), a sample holder, a dispersive element (grating monochromator), and an optical detector sensitive to the dispersed light. [Pg.133]

UV spectra were obtained with a Varian spectrometer (Cary 15 and 17). Fluorescence, phosphorescence spectra, and the zero-field splitting parameters D and E of the triplet state were determined at 1.3K with an apparatus (31) for optical detection of magnetic resonance (ODMR) which was similar to the one described by Zuclich et al. (32). [Pg.338]
