The {sup 150}Nd({sup 35}Cl,4{ital n}){sup 181}Ir and {sup 150}Nd({sup 34}S,4{ital n}){sup 180}Os reactions have been used to study the lifetimes of high-spin states in {sup 181}Ir and {sup 180}Os using the recoil-distance technique. The lifetimes of four states in {sup 181}Ir and three yrast states in {sup 180}Os have been determined. The mean weighted values of quadrupole moments deduced for the measured rotational transitions between yrast states in {sup 181}Ir and {sup 180}Os, {ital Q}{sub 0}=(6.0{plus minus}0.2) {ital e} b and {ital Q}{sub 0}=(6.1{plus minus}0.4) {ital e} b, respectively, are equal within experimental errors.
