The proton magnetic resonance spectrum of biphenyl has been observed in dilute solution with d-chloroform and tetramethylsilane as the solvents. Theoretical analyses of these spectra were carried out with the aid of additional data provi... RE Mayo,JH Goldstein - 《Molecular Physics》 被引量: 41...
Sam- ples were dissolved in d-chloroform prior to the analy- sis. Four transients of pulse sequence Zg30 were used to acquire 1H spectra and 99 transients of Zgpg30 pulse were used for acquiring 13C data. Temperature of the probe was 13 Variations in GC鈥揗S Response 253 maintained at...
Concentration dependence of the 1H- and 29Si-NMR chemical shifts of tetramethyldisiloxanediol in deuterated chloroformNMR spectroscopyOrganosilicon chemistrySilanolIn solid state and highly concentrated solutions, silanols are connected via strong intermolecular hydrogen bonding of the end-groups. However, ...
In this paper, chemical shift values of tetramethyldisiloxartediol M-2(OH) are presented with regard to their change in dependence on concentration in deuterated chloroform and on temperature. These values are compared to values found in solid state NMR spectroscopy. (C) 2001 Elsevier Science B...
