Hall Effect Experiment - University of Tennessee

systems, at very low temperature and large fields, the Hall resistance show a step-like (rather than linear) dependence on B. These steps are completely independent of the type of sample and quantitized to values h/e2m, where m is an integer. This is the famous Quantum Hall Effect4. The fundamental quantum of Hall resistance is h/e2 =25,813Ω ...

Infrared Spectroscopy and Mass Spectrometry

Infrared Spectroscopy and Mass Spectrometry Introduction It is fundamental for an organic chemist to be able to identify, or characterize, the new compound that he/she has just made. Sometimes this can be achieved by a chemical means, such as determining the elemental composition and molecular weight.

Microwave (Rotational) Spectroscopy

From microwave spectroscopy, bond lengths can be determined with a correspondingly high precision, as illustrated in this example. From the rotational microwave spectrum 35of 1H Cl, we find that B = 10.59342 cm-1. Given that 35the masses of 1H and Cl are 1.0078250 and 34.9688527 amu, respectively, determine the bond
