2021-04-22 21:40 In chemistry, isomers are molecules or polyatomic ions with identical chemical formulas but distinct arrangements of atoms in space. Isomers do not necessarily share similar properties. Two main forms of isomerism are structural isomerism (or constit ... дальше
2021-04-22 21:40 The magnetic nucleus undergoes spin level splitting under the action of an external magnetic field. When absorbing external electromagnetic radiation, a transition of nuclear spin level will occur, resulting in nuclear magnetic resonance. In organic ... дальше
