Modification of an adiabatic heat pulse method is proposed for specific heat measurements at low temperatures in which a resistance thermometer also serves as heater for the sample. Specific heat data of Cu(C,H,N,) (H,O),SO, from 2 to 9 K measured using the modified method agree reasonably well with
## Abstract Most established NMR thermometers rely on temperature‐dependent chemical shift differences measured from samples that are either neat or concentrated solutions (e.g. ethylene glycol, methanol). These are unsuitable for modern cryoprobes on account of strong radiation damping resulting f
## Abstract By means of ^27^Al, ^1^H, ^17^O and ^13^C NMR spectroscopy the structure of the methylaluminoxane (MAO) cocatalyst of Kaminsky‐Sinn catalysts was investigated. We have found that the ^27^Al NMR resonance line of MAO is extremely broad at room temperature (δ ≈ 60, Δω~1/2~ 50 ± 10 kHz). A
We discuss a method to determine temperature in a static NMR experiment from the temperature variation of the lead nitrate peak shift.
