Abstract

Simple group‐theoretical arguments are used to derive the dependence of the relaxation transition probabilities with participation of an arbitrary number of phonons on the orientation of an external magnetic field relative to the crystal axes of the paramagnetic samples. The system of paramagnetic ions with arbitrary spin is investigated in the case of weak magnetic field, when the Zeeman splitting is much smaller than the crystal field splitting. However, the results may be directly transferred to the opposite case of |𝒳~z~|≫|𝒳~cr~|. An example of application of the results obtained is considered.

## Abstract The influence of the stretched line wings on the spin‐lattice (longitudinal) relaxation rate is considered. It is shown that in the spin‐system with long line wings even the direct process of the spin‐lattice energy exchange may involve mainly nonresonant phonons. The component of the r

A murine anti-human melanoma monoclonal antibody fragment was labeled with gadolinium and its proton relaxation efficiency compared to controls at frequencies ranging from 2 to 300 MHz. Relaxation time variations were about 30-40% in 10-15 microM solutions. The labeled fragment showed proton relaxat
