Shift reagentsDeuterium labeling1- aminocyclo-propane-1-carboxylic acidThe two sets of diastereomeric hydrogen atoms cis and trans to the carboxylate of 1-aminocyclopropane-1-carboxylic acid (ACC) were differentiated by a 1H-nmr study. The measurement of the 1H-nmr spectrum of ACC at pH 3.8 ...
An aliphatic carboxylic acid is a type of carboxylic acid that is conjugated by the mitochondrial amino acid system, involving the activation of fatty acids to their CoA thioesters for further metabolic processes.

4). Firstly, the interactions between the carboxylic acid, arene, and triflic anhydride were monitored by 13C NMR. As shown in Fig. 4a, a significant chemical shift from 181.1 to 189.6 ppm was observed after the addition of Tf2O to the propionic acid 1 solution, indicating the rapid...
7. The most low field signal resonated at 15.6 ppm was unambiguously assigned to carboxylic proton. The complete1H NMR chemical shift assignment (ppm) and coupling constants [J(H, H)/(Hz)] with two-dimensional (DQF-COSY) of dimer of phenazine-1-carboxylic acid natural product are shown in...

The proton nuclear magnetic resonance spin鈥搇attice relaxation time has been successfully used to evidence the reorientation of the imidazolium rings in carboxylic acid salts of imidazole: imidazolium oxalate, imidazolium adipate monohydrate and diimidazolium suberate. The process occurs in the temperature...
NMR and IR spectroscopy have been used in studying the equilibrium in the reaction of proton transfer from thiocarboxylic acids RCOSH [R=CH3 (a), C6H5 (b) or CH2Cl (c)] to -collidine (d), and also the kinetics of CH/NH proton exchange between protonated -collidine and excess RCOSH...
