A series of halomethyl cations was prepared and studied by 13C NMR spectroscopy. Their structures and 13C NMR chemical shifts were also calculated by ab initio/DFT/GIAO-MP2 methods. The δ13C of trihalomethyl cations CX3+ (X = Cl, Br, I) and dimethyl

Ca 2+ sensors of high sensitivity and stability can be fabricated by coating Si/SiO 2 devices with specially synthetisized Langmuir-Blodgett (LB) membranes. The Ca 2+ sensitive LB-material is an amphiphilic copolymer containing covalently bound ionop

Comparison of ab initio/IGLO calculated 1 H, 13 C, and 29 Si NMR chemical shifts with the experimental data on trimethylsilyl perchlorate and related derivatives supports the conclusions that no long-lived persistent trimethylsilicenium ion has been

In a series of α,α-difluoroarylcarbenium ions 1 , one bond 13 C- 19 F coupling constants and the 19 F chemical shifts at the cationic center have been used as criteria to follow the extent of fluorine non-bonded electron pair back donation. The ele
