摘要

The temperature dependence of the O-17 nuclear quadrupole resonance (NQR) frequencies has been measured in commercial trinitrotoluene by highly sensitive nuclear quadrupole double resonance techniques. The N-14 NQR frequencies have been measured in the same sample for comparison. In contrast to the N-14 quadrupole coupling constant, the O-17 quadrupole constant increases with increasing temperature.
