Rotational Constants. Moments of Inertia. Geometrical Structure

4 Rotational Constants. Moments of Inertia. Geometric Structure 

For three isotopic species in their vibrational ground states, the following rotational constants (in MHz) were derived from the microwave spectrum [1], see also the tables [2] of molecular constants from microwave spectroscopy (for axis system, see Fig. 1 [1]). 

Constants for vibrationally excited states of 02F2 are also reported [1,2].  

The above rotational constants correspond to the following effective moments of inertia (in amu-A ) [1]  

The following values of the bond distances r (in A), the bond angle a(OOF), and the dihedral angle 4 (see Fig. 2) were derived from the above rotational constants [1 ], see also [3]. The type of the respective geometric parameter ( substitution or effective ) has been added according to the tables [4] of molecular structures see also tables [5] of structural data.
