Abstract
We show that a recently developed method for generating bounds for the discrete energy states of the non-hermitian potential (Handy 2001) is applicable to complex rotated versions of the Hamiltonian. This has important implications for extension of the method in the analysis of resonant states, Regge poles, and general bound states in the complex plane (Bender and Boettcher (1998)).
