Ro-vibrational dynamics of N2O in superfluid 4He nano-droplets

In this paper we use the important interferences of Macro-Orbital theory of superfluidity clubbed with several factors that can change the rotational constant (B) and vibrational frequency of N2O in 4HeN-N2O clusters with N to account for the results of their recently reported spectroscopic studies which conclude that: (i) in spite of the fact that 4He atoms provide an interactive medium, the rotational spectrum of the clusters shows sharp peaks, similar to that of the molecule in gaseous state, indicating that the molecule rotates like a free rotor, (ii) B decreases monotonically from N = 1 to 6, remains nearly constant for N = 6 to 8 and increases for N = 9 to 10 with small oscillations there after and (iii) vibrational frequency exhibits blue shift for N = 1 to 5 and a red shift for higher N.
