Abstract
We have calculated pure rotational transitions of water molecule from a kin etic energy operator (KEO) with the z-axis perpendicular to the molecular p lane. We have used rotational basis functions which are linens combinations of symmetric top functions so that all matrix elements are real. The calcu lated spectra agree well with the observed values.
