Photo-degradation of [ 14 C]-thifensulfuron methyl has been investigated in aqueous media using a light source which simulates sunlight. Degradation of thifensulfuron methyl proceeds predominantly via sulfonylurea bridge ipso-contraction, and via cle

In this paper, we detail the results of 1H–15N correlation data obtained via 13C–15N coupling at natural abundance on a number of classes of azoles including pyrazoles, imidazoles and triazoles. The experiment produces data that is highly complem

Measurement of 1 H-15 N and 13 C-15 N coupling constants at natural abundance is demonstrated to be a reliable and generic method to determine the configuration of oximes, hydrazines, and related systems. Data on 1 H-15 N and 13 C-15 N coupling const

The availability of cryogenically cooled probes permits routine acquisition of data from low sensitivity pulse sequences such as inadequate and 1,1-adequate. We demonstrate that the use of cryo-probe generated 1,1-adequate data in conjunction with HM

Decoupling 19 F during data acquisition is extensively used to simplify proton spectral interpretation of fluorinated compounds. Decoupling applied during the acquisition time (t2) of a 2D experiment, however, only produces partially decoupled spectr

We propose a pulse sequence, HCNMBC for multiple-bond H–(C)–N correlation experiments via one-bond 1 J (C,H) and one- or multiple bond n J (N,C) coupling constants (typically n = 1–3) at the natural isotopic abundance. A new adiabatic refocussi

Two-dimensional NMR spectra correlating both (1)H and (19)F nuclei with either (13)C or (15)N, are recorded at the same time, using a 600-MHz broadband radio frequency probe feeding independent (1)H and (19)F receiver channels. This technique, known

Analysis of the 19F chemical shifts of trifluoromethylpyrazole regioisomers has shown that while chemical shift is in general a reliable predictor of regiochemistry in this series, there is a narrow chemical shift range in which the two isomers overl
