Proton nmr parameters are reported for DMSO-d6 solutions of two receptor-selective substance P analogues: Ac[Arg6, Pro9]SP6-11, which is selective for the NK-1 (SP-P) receptor and [pGlu6, N-MePhe8]SP6-11, which selectively activates the NK-3 (SP-N) receptor. Full peak assignments...
NMR and solvation of ions in non-aqueous solvents Solvation of ions as a microscopic property is understood to be given by certain time independent and time dependent probability functions which describe t... HG Hertz - 《Pure & Applied Chemistry》 被引量: 7发表: 1982年 Copper Phthalocyanine ...

Generally, the 1H-15N HSQC spectrum which shows one cross peak for each non-proline residue in a protein, serves as a fingerprint of the conformational state of the protein. The HSQC spectrum of DLC8 in deuterated DMSO at 45 °C is shown in Fig. 1. The narrow chemical shift dispersion...

Interestingly,from MDSC curves of HEWL in aqueous solution without DMSO,a small and symmetrical peak in front of the main transition (I)was observed marginally,which was regarded as a pre ⁃transition (II).Specially,this small and marginal peak could not be found in aqueous solution containing...
The structures of the polymers 3 were supported by H-1 NMR, B-11 NMR, and IR spectra. The obtained polymers were soluble in common organic solvents such as tetrahydrofuran, chloroform, and benzene. The peak due to the pi-pi* transition of 3a was observed at 415 nm, which was ...

(cf. Fig.S-2) in the force field simulations shows a slight deviation from the AIMD-based results regarding the location and intensity of the initial peak. This difference is observed in both force field simulations utilizing the literature force field and BILFF. It underscores the challenge ...
