## Abstract Carbonβ13 NMR chemical shifts have been measured in a number of binary mixtures of normal alkanes. Intrinsic solvent shifts are deduced from the shifts and the relevance of some small substituent effects in alkanes is discussed. A comparison is made between solvent effects and thermally

Abstract
The ^13^C NMR shift parameters and couplings to tin are reported for nine phenyltin halogenides and seven phenyltin chalcogenides, as well as the T~1~ results for Ph~2~SnTe. A pronounced linear dependence of all coupling constants on the paraβcarbon shift is discussed.

The uC NMR spectra of 24 1,3-dioxoIane derivatives are reported in an attempt to propose parameters for the C-2, C-4 and C-5 shifts from the %Me and 4-Me substituents, based on the ring stereochemistry. These parameters are obtained from simultaneous equations, and clearly agree with those Calculate
## Abstract The kinetics of solventβfree reactions can be followed in situ by ^13^C nuclear magnetic resonance (NMR) spectroscopy, provided that the reaction mixture can be maintained liquid at the monitoring temperature. The pros and cons of the technique and the correct translation of the signal
