In a subsequent analysis the Euclidean norm kDVk of each sampled vector DV is computed, and the test isobar yielding the smallest norm is considered to be the most accurate approximation to the experimental reference. In the following, the Euclidean norm of the error vector kDVk will also synonymously be denoted as the accuracy of the underlying test isobar [21, 22]. 3 Cluster Equilibrium The methodology presented so far covers the treatment of particle interactions on an accurate local scale (intracluster interactions via first principles computations) and an approximate non-local scale (intercluster interactions via a van der Waalslike mean field term) as well as the approximate treatment of the excluded volume in terms of atomic van der Waals radii.
1 The Rigid Rotor Harmonic Oscillator Model 17 The generalization of Eq. 36 to asymmetric top structures can be achieved by inserting the classical Hamilton function of a rigid rotor into the classical partition function (see Eq. 1) and carrying out the integration. The result is given as  p1=2 2Ia kB T 1=2 2Ib kB T 1=2 2Ic kB T 1=2 qrr ðTÞ ¼ r "2 h h2 " "h2 1=2 p1=2 T3 ¼ ; r Ha Hb Hc ð2:37Þ where Hða;b;cÞ denotes the rotational temperature associated with the principal moments of inertia Ia, Ib, Ic according to Hða;b;cÞ ¼ "2 h 2Iða;b;cÞ kB : ð2:38Þ It is apparent that this result reduces to the correct expression for a spherical top in the limit Ia = Ib = Ic.
