ABSTRACT
We report 63Cu nuclear quadrupole resonance (NQR) measurement of Cu2O under pressure up to about 10 GPa at low temperatures. Because the lattice parameter of Cu2O changes with increasing pressure, the electric field gradient at the Cu site also changes correspondingly with pressure. This enables us to use the Cu2O as an in situ manometer for high pressure nuclear magnetic resonance/NQR up to about 9 GPa.

    The pure rotational spectrum of CCl2 in the ground state was observed for the first time in the millimeter- and submillimeter-wave region. The CCl2 molecule was generated directly in a free space cell by a dc glow discharge in CCl4 . Several transitions showed hyperfine splittings arising from...
