Irradiated betaine hydrochloride: the free radical, N(CH3)3+
Australian Journal of Chemistry, 1973The e.s.r. parameters for the free radical, N(CH3)3+, trapped in monoclinic single crystals of ?-irradiated betaine hydrochloride, have been investigated. The hyperfine splittings have isotropic values, ANiso = 2.26 mT and Aß-Hiso = 2.79 mT, and the isotropic value of the g-tensor is 2.0039.

The crystal structures of 12-hydroxynorfluorocurarine (vincanidine) isolated from the plant Vinca erecta, its hydrochloride monohydrate, quaternary salts — chloromethylate and iodomethylate, and the quaternary base (zwitterionic betaine) have been studied. The asymmetric centers of the molecules have the 3S, 7R, 15S configuration.

We show here that betaine hydrochloride (BHC), a co-product of the carbohydrate industry, can be used for the design of cheap and safe media capable of promoting the dehydration of fructose and inulin to HMF. In particular, in these BHC-based media, HMF was obtained with up to 84% yield, thus offering a competitive route to the traditional imidazolium ...

Radiation Effects and Defects in Solids, 2015
Gamma irradiated powders of glycine anhydride and betaine hydrochloride have been investigated at room temperature by electron paramagnetic resonance (EPR). In these compounds, the observed paramagnetic species were attributed to the R1 and R2 radicals, respectively. It was determined that the free electron interacted with environmental protons and 14N

Electron Spin Resonance in Irradiated Single Crystals of Betaine Hydrochloride
The Journal of Chemical Physics, 1964Radicals trapped in electron-irradiated single crystals of betaine hydrochloride, (CH/sub 3/)/sub 3/N/sup +/ CH/sub 2/COO/sup -/, were s tudied. Irradiation was carried out at room temperature with 1 Mev electrons. The dosages ranged from 1 to 5 Mrad and had no apparent effect on the nature of the free radicals formed in betaine. The spectrum along the
