## Abstract In order to obtain some insight into the structure of an ultrahighβmolecularβweight polyethylene sample, ^13^C CP/MAS NMR experiments have been carried out at temperatures from 23 to β108Β°C. The peak for the crystalline component moves upfield with a decrease in temperature, which is co
The fragmentation and redistribution reactions of [Rh 4 (CO) 12-x {P(OPh) 3 } x ] (x = 1-4) with carbon monoxide have been studied using high-resolution, high-pressure NMR spectroscopy. Under the conditions of efficient gas mixing in a high-pressure NMR bubble column, [Rh 4 (CO) 9 {P(OPh) 3 } 3 ] fr
