METHOD OF MUTATION RELAXOMETRY Russian patent published in 1997 - IPC

FIELD: study of structure of chemical compounds. SUBSTANCE: method includes periodic action on specimen by two HF pulses with carrier frequency equalling the frequency of excited transition, saturation, detuning and determination of time T₂₉ of transverse relaxation in rotating coordinate system. Object of investigation is used in form of specimen having quadrupole nuclei with multilevel energy spectrum. First, specimen is acted upon by single pulse with carrier frequency equalling the frequency of transition having common energy level with exciting transition. Pulse duration is set within the ranges T*2

< t_w< T₂, and amplitude is set by maximum each signal whose envelope is used to find transverse relaxation time T₂₈ of transition on which single pulse acts. EFFECT: higher efficiency. 1 dwg
