Title: The Innovations of Junjiro Imaizumi: A Pioneer in Nuclear Magnetic Resonance Spectroscopy
Introduction: Junjiro Imaizumi is a distinguished inventor based in Tokyo, Japan. He is recognized for his significant contribution to the field of nuclear magnetic resonance (NMR) spectroscopy, where his innovative approach has advanced the high-resolution analysis of solids.
Latest Patents: Imaizumi holds a patent for high-resolution NMR spectroscopy in solids. His patent details a method that utilizes magic angle spinning and cross-polarization techniques. The sample is rotated by a spinner at a high speed, oriented at the magic angle of 54.44° concerning the static magnetic field. By applying a 90-degree pulse to abundant nuclear species such as hydrogen-1, which are coupled to dilute nuclear species like carbon-13, he enhances the measurement accuracy. Additionally, a spin-locking pulse or sequence is applied to the abundant nuclear species, followed by an observing pulse targeted at the dilute nuclear species. This sophisticated method enables the detection of free induction decay signals from dilute nuclear species while maintaining the pulse parameters through amplitude modulation at a low frequency.
