We can deduce the rotational constant B since we know the distance between two energy states and the relationship \[F(J)=BJ(J+1) onumber \] The distance between J=1 and J=3 is 10B, so using the fact that B = 14,234 cm-1, B=1423.4 cm-1.

The measurement and identification of one spectral line allows one to calculate the moment of inertia and then the bond length. b Recalculated as r e = [505 379.006(51) / µ r B e] 1/2 with units as given in table. B is called the rotational constant, and is traditionally given as its wavenumber equivalent, B ~ = B / h c, in units of inverse centimeters (cm -1). B = rotational constant, units cm-1 4.

3. Molecular Constants from Rotational Spectra. We now consider what information about K is the angular momentum quantum number for rotation about the symmetry axis .

J values up to 48 for the 2-0 band and up to -35 for the 3-1 and 4-2 bands were measured. Using previous measurements of the 2-0 band and the results of microwave determinations a set of rotation-vibration constants was deduced. The vibrational constants in vacuum wave numbers are: we = 2169.8232, wexe = -13.2932, eaeye = 0.01144.

Rotational constants are inversely related to moments of inertia: B = h / (8 π 2 c I) Where B is the rotational constant (cm-1) h is Plancks constant (gm cm 2 /sec) In this video will will use the rotational constant of HI to calculate its bond length. We will follow three steps in doing this calculation. First we will c (December 23, 1968) This paper li sts, in order of increasing value, the " B" rot ational constants of most of the linear and symmetric top molecules which have been observed by microwave spectroscopy.

Determining the rotational constant B . enables you to calculate the bond length R. The allowed transitions for the diatomic molecule are regularly spaced at interval 2B. The measurement and identification of one spectral line allows one to calculate the moment of inertia and then the bond length.

D is small; where since, → D/B smaller for “stiff/hi-freq” bonds B B … centrifugal distortion constant. B υ may be obtained from the equilibrium geometry of the molecule using the following relationships (equations 11 & 12), where B e is the equilibrium rotation constant, α is the anharmonicity correction factor to the rotational energy and I e is the equilibrium moment of inertia. B υ=B … Angular Velocity.

Selection rules: (1) permanent dipole moment, 5. Spacing between lines of in rotational spectra of rigid diatomic molecules is constant and equal to 2B cm-1. For the example of the molecule SPF 2 H, we were fortunate enough to be able to measure several J=1->2 transitions, which permit a rather straightforward calculation of the rotational constants.
