The phosphazene compound that acts as a superbase is

If a molecule emitting a radiation of frequency \(3.100 \times 10^9\) Hz approaches an observer with a relative speed of \(5.000 \times 10^6\) m s\(^{-1}\), then the observer detects a frequency of ___________ \( \times 10^9 \) Hz. (rounded off to three decimal places) [Given: Speed of light \(c = 3.000 \times 10^8\) m s\(^{-1}\)]

Rigid rotor wavefunctions are given by \( Y_{l,m}(\theta, \phi) \). The wavefunctions \( Y_{1,0}(\theta, \phi) \) and \( Y_{2,0}(\theta, \phi) \) are given below: \[ Y_{1,0}(\theta, \phi) = \sqrt{\frac{3}{4\pi}} \cos \theta \qquad Y_{2,0}(\theta, \phi) = \sqrt{\frac{5}{16\pi}} (3\cos^2 \theta - 1) \] For a non-polar diatomic molecule, the value of transition dipole moment integral for the transition between \( Y_{1,0}(\theta, \phi) \) and \( Y_{2,0}(\theta, \phi) \) is equal to:
