摘要：

We present an experimental investigation of the C(3)(1)Sigma(+) and c(2)(3)Sigma(+) states of KCs using two-colour polarisation labelling spectroscopy (PLS) technique. Pointwise potential energy curves are generated for both states using the inverted perturbation approach (IPA) method. The experimental pointwise potentials and molecular constants T-e, omega(e), and R-e are compared with theoretical calculations. (C) 2017 Elsevier Ltd. All rights reserved.
