Abstract:
1. A solid-state NMR sample tube capable of sealing a sample, to be investigated by solid-state NMR spectroscopy, the sample tube being capable of being spun at high speed, where high speed is from a few kHz to tens of kHz, via gas bearings which are formed between the sample tube and a tube-holding mechanism that holds the tube by being supplied with a gas, said sample tube comprising: a hollow cylinder having opposite ends, at least one of the ends being open in order to form an opening; and a cover mounted in the opening, where E is the longitudinal elastic modulus, ρ is the density, λ is 4.730, c is the sonic velocity (340 m/s), and B is a factor which is dependent on (L/D) and which is a value interpolated or extrapolated from each point in the following table:
