発明の名称 (英語) NUCLEAR MAGNETIC RESONANCE DEVICE, AND MICROCRYSTALLINE STRUCTURE ANALYSIS METHOD NEW
発明の概要(英語) The objective of the present invention is to provide a nuclear magnetic resonance device and a microcrystalline structure analysis method with which a nuclear magnetic resonance signal that is effective for crystal structure analysis can be detected, even with a specimen with which said effective nuclear magnetic resonance signal cannot conventionally be detected. A nuclear magnetic resonance device 1 which excites nuclear magnetic resonance by radiating pulsed electromagnetic waves at a sample disposed in a static magnetic field, and detects a nuclear magnetic resonance signal generated by the nuclear magnetic resonance, is provided with: a static magnetic field source 4 which generates the static magnetic field; a transmitting and receiving unit 5 for radiating the electromagnetic waves and detecting the nuclear magnetic resonance signal; a rotating mechanism 10 which causes a sample container 2 in which microcrystals 3 are suspended to rotate at a variable speed, in such a way that the sample container 2 rotates at a variable speed in the static magnetic field in order to apply a time varying magnetic field thereto to three dimensionally orientate the microcrystals; and a control unit 7 for controlling the transmitting and receiving unit 5 to radiate the electromagnetic waves in synchronism with the variable speed rotation of the sample container 2.
従来技術、競合技術の概要(英語) BACKGROUND ART
, MAS(Magic Angle Spinning) as to analyze a crystal structure of the object using a nuclear magnetic resonance method (NMR device) has been known. The nuclear magnetic resonance apparatus, the sample is inclined in the magic angle with respect to the static magnetic field, for example 5KHz-20KHz is rotated at high speed, during the rotation of the sample irradiated by the electromagnetic wave generated when the nuclear magnetic resonance (NMR; Nuclear Magnetic Resonance) signal is detected, according to the present invention to analyze a crystal structure of the sample (see Patent Document 1). In addition, as to analyze a crystal structure of the object, the sample is suspended in a time-varying magnetic field to the micro-crystal is applied, the three-dimensional orientation ( crystallization) to microcrystalline the result of analysis by X-ray irradiated X-ray structure analysis apparatus has been known (see Patent Document 2).
