Soc. 88, 420 (1966).""Author Institution: Department of Physics and Department of Chemistry, Mississippi State UniversityThe microwave spectrum of 1,3-cycioheptadiene has been studied in the X-band [FIGURE] and R-band frequency regions. Preliminary analysis gives A = 3419.25, B = 3297.15, and C = 1799.93 MHz for the ground vibrational state rotational constants. These rotational constants are reasonably consistent with the electron diffraction $structure,^{1}$ where the carbon skeleton is coplanar except for the $C_{6}$ atom which is out of the plane. Further confirmation of the structure should come from the dipole components in the principal axis system. Stark effect measurements are in progress
