Overhauser a W (2 results)

Lancaster and New York, American Institute of Physics, 1953. Lex8vo. Volume 92, October 15, No. 2, 1953 of "The Physical Review", Second Series. In the original printed blue wrappers. A 5 cm long tear to lower part of spine. Back wrapper with three larger tears to upper layer of paper, loss of a few letters. Internally a nice and clean copy. Pp. 411-415. [Entire issue: Pp. 215-546]. First edition of Overhauser's seminal paper on dynamic nuclear polarization (DNP) today known as The Overhauser Effect or Nuclear Overhauser effect.Nuclear magnetic resonance (NMR) spectroscopy is an important technique for the determination of structures in material science and structural biology. For liquid-state NMR the only DNP mechanism currently known is the Overhauser Effect. For solid-state a variety of different DNP-mechanisms can be used such as the thermal-mixing, cross-effect or the solid-effect.

Soft cover. Condition: Very Good. OVERHAUSER, A.W. "Polarization of Nuclei in Metals" in "The Physical Review." volume 92 number 2, 15 October 1953, the issue containing pp 215-546 with the Overhauser on pp 411-415. Original wrappers. VG+ (a 7.5/10) copy, really quite nice, crisp and tightly bound. First edition of the first appearance of the Overhauser Effect. [++] The Overhauser [or the Nuclear Overhauser Effect, or NOE] effect, also known as "dynamic nuclear polarization," was predicted by Overhauser in [the paper offered here]. In any sample containing paramagnetic molecules in solution (such as biological sample or animal containing free radicals) interactions will occur between the unpaired electrons and the NMR-sensitive hydrogen nuclei (protons) in the solvent water molecules. In the Overhauser effect an NMR experiment is carried out to detect an NMR signal from the water protons, and at the same time the sample is irradiated at the EPR frequency to excite the unpaired electron spins. The result of the EPR irradiation can be a significant enhancement (or amplification) of the measured NMR signal, relative to the signal obtained without EPR irradiation."--Chandran Karunakaran, Murugesan Balamurugan, in "Spin Resonance Spectroscopy, 2018" via ScienceDirect online. [++] "The NOE developed from the theoretical work of American physicist Albert Overhauser who in 1953 [the paper offered here] proposed that nuclear spin polarization could be enhanced by the microwave irradiation of the conduction electrons in certain metals."--Wikipedia on the Overhauser Effect.
