Abstract
The vapor pressures and vapor molecular weights of the copper and yttrium b eta -diketonate MOCVD precursors CU(C11H19O2)(2) (c) and Y(C11H19O2)(3) (c) were measured by a;torsion-effusion/mass-loss method in the ranges (346 to 375) K and (361 to 387) K, respectively. The molecular weight data indicat e that the saturated vapors of both precursors are highly monomeric. Vapor pressures, estimated to be accurate within 5%, are presented in equation fo rm for reliable extrapolation to higher temperatures. The results are compa red with other determinations in the literature.
