We report {sup 63}Cu nuclear quadrupole resonance (NQR) measurement of Cu{sub 2}O under pressure up to about 10 GPa at low temperatures. Because the lattice parameter of Cu{sub 2}O changes with increasing pressure, the electric field gradient at the Cu site also changes correspondingly with pressure. This enables us to use the Cu{sub 2}O as an in situ manometer for high pressure nuclear magnetic resonance/NQR up to about 9 GPa.
