Analysis of a first-time recorded rotational structure of the v' = 45 <- v(n) = band of the (1)0(u)(+)(5(1)P(1)) <- (XOg+)-O-1 transition in Cd-228(2) is presented. In the interpretation, an influence of a nuclear spin intensity alternation and rotational levels symmetry properties are taken into account. From the analysis, the B-v(=0)n 0.0206 +/- 0.0005 cm(-1) and B-v'(=45) 0.0277 +/- 0.0005 cm(-1) rotational constants, and the R-e" = 3.77 +/- 0.04 angstrom and R-e' = 2.94 +/- 0.03 angstrom bond lengths are determined for the (CdCd)-Cd-114-Cd-114. The obtained value of R-e" is close to that obtained with an assumption of a covalent admixture to the dominant van der Waals bonding of Cd-2 and is smaller than that derived with an assumption of pure dispersion forces.
