PH 511 General Physics Laboratory II. M.Sc. III Semester. Instruction Manual. Department of Physics. INDIAN INSTITUTE OF TECHNOLOGY GUWAHATI This Lab manual contains eight experiments from different areas of Physics. .. Adjust Frequency and Sensitivity knobs of the ESR Spectrometer and the Sensitivity.
Using ESR (Electron Spin Resonance, also known as Electron Paramagnetic Resonance) you will be measuring one of the best known quantities in all of physics, the famous gs- factor of the electron. This will be achieved by looking for the “spin-flip" transition of a free (unpaired) electron exposed to a magnetic field.
1. Instruction Manual. PH511: Physics Laboratory-III. DEPARTMENT OF PHYSICS. INDIAN INSTITUTE OF TECHNOLOGY GUWAHATI. July- Nov 2014 This calls for a thorough study of the instruction manual before coming to .. spin resonance (ESR) can be observed in RF range with magnetic field of a few gauss or in a.

In doing this (without external magnetic field), “R" on the resonator is brought to its central position and “C" to the lefthand stop. On the ESR.
This Lab Manual will provide the necessary information to perform the experiments in a reason- able time. It cannot substitute reading of relevant literature nor will it work as a "cookbook" – experimental expertise has to be aquired through your own exercise and careful thoughts about the experiments. However, if well
Apparatus: ESR setup which includes Helmholtz coils, R.F. oscillator and the test sample, and in addition, a cathode ray oscilloscope (CRO). Theory. Background . way of changing the phase of, say, the Y signal, one can adjust the phase manually so that the four peaks merge into two. Getting the numbers. We have the
Electron spin resonance (ESR) is a useful tool for investigating the energy absorption spectra of many materials with unpaired electrons (paramag- netic materials). The molecule will have an intrinsic magnetic dipole mo- ment due to the unpaired electron. ESR is a purely quantum mechanical effect. It relates the interaction

11 Jan 2016 The erythrocyte sedimentation rate (ESR) is a common hematological test for nonspecific detection of inflammation that may be caused by infection, some cancers and certain autoimmune diseases. It can be defined as the rate at which Red Blood Cells (RBCs) sediment in a period of one hour. PRINCIPLE
