核磁共振（NMR）

介紹

核磁共振（NMR）的概念介紹

• 觀察兩個(gè)質(zhì)子和無氟歲差
• 發(fā)現(xiàn)居里法和自旋 - 晶格弛豫
• 測量自旋 - 晶格弛豫的函數(shù)：
  • 順磁離子濃度
  • 粘性
  • 溫度
• 觀察和測量氟質(zhì)子-J-耦合
• 測量**超值的g的_質(zhì)子 /克_氟
• 精確測量地球磁場
• 聽到內(nèi)置音頻系統(tǒng)的歲差
• 逆市線圈，為提高信號(hào)噪聲研究
• 檢查調(diào)諧信號(hào)噪聲的影響

這是很難想象 一個(gè)大學(xué)物理或化學(xué)專業(yè)畢業(yè)的，沒有進(jìn)行某種磁共振實(shí)驗(yàn)。一直以來，核磁共振，并明確提出將繼續(xù)是一個(gè)重要的實(shí)驗(yàn)工具，在阿森納的物理學(xué)家，化學(xué)家，生物學(xué)家和醫(yī)學(xué)診斷專家。在量子計(jì)算的*近的事態(tài)發(fā)展似乎表明，磁共振可能成為計(jì)算機(jī)科學(xué)的硬件基礎(chǔ)平臺(tái)。是毫無疑問，這種類型的光譜學(xué)專業(yè)的學(xué)生應(yīng)該有一個(gè)基本的了解。

Introduction

A Conceptual Introduction to Nuclear Magnetic Resonance (NMR)

• Observe both Proton and Fluorine Free Precession
• Discover both the Curie Law and Spin-Lattice Relaxation
• Measure Spin-Lattice Relaxation as a Function of:
  • Paramagnetic Ion Concentration
  • Viscosity
  • Temperature
• Observe and Measure Proton-Fluorine J-Coupling
• Measure Absolute Value of g_proton/g_fluorine
• Precisely Measure Earth's Magnetic Field
• Hear the Precessions on Built-In Audio System
• Study Bucking Coils for Enhancing Signal-to-Noise
• Examine Effects of Tuning on Signal-to-Noise

It is hard to imagine a college physics or chemistry major graduating without having performed some kind of magnetic resonance experiment. Nuclear magnetic resonance has been， and clearly will continue to be， an important experimental tool in the arsenal of physicists， chemists， biologists and medical diagnosticians. Recent developments in quantum computing seem to indicate that magnetic resonance might become the basic platform of computer science hardware. There is no doubt that science majors should have a basic understanding of this type of spectroscopy.
