We present an accurate potential energy curve of the B {sup 1}{Pi} state in the LiCs molecule for which vibrational levels between v{sup '}=0 and v{sup '}=35 (bound by 11.4 GHz) were measured by photoassociation spectroscopy in an ultracold ensemble of {sup 7}Li and {sup 133}Cs atoms. By the combination of conventional spectroscopic data of the B-X system and the new photoassociation measurements a very precise value of the dissociation energy of the ground state X {sup 1}{Sigma}{sup +} of LiCs was determined to be D{sub 0}=5783.495(5) cm{sup -1}.
