Proton Magnetic Resonance Study of the Amino Group of Thioacetamide (TA) Ⅰ. Quadrupole Relaxation Effects in NH2 of Thioacetamide
Jae-Ryun Suhr, Chang-Ju Yoon*, Seong-Gu Ro, Young-Sang Choi
Nitrogen-14 quadrupolar relaxation has been observed in the amino proton nmr spectra of TA in acetone and methanol solutions over the temperature range -83℃ to +35℃. The proton nmr lineshapes were analyzed to yield a 14N spin lattice relaxation time (T1)N as a function of temperature. Activation energies and correlation times at 25℃ for the molecular reorientation in the two solution phases have been calculated and the results are discussed.
