In this paper we derive representation formulae for the second factorial moment measure of the point process of nodes and the second moment of the number of vertices of the typical cell associated with a stationary normal Voronoi tessellation in ℝd. In case the Voronoi tessellation is generated by a stationary Poisson process with intensityλ> 0 the corresponding pair correlation functiongV,λ(r) can be expressed by a weighted sum ofd+2 (numerically tractable) multiple parameter integrals. The asymptotic variance of the number of nodes in an increasing cubic domain as well as the second moment of the number of vertices of the typical Poisson Voronoi cell are calculated exactly by means of these parameter integrals. The existence of a (d− 1)st‐order pole ofgV,λ(r) atr= 0 is proved and the exact value of limr→0rd–1gV,λ(r) is determined. In the particular casesd= 2 andd= 3 the graph ofgV,1(r) including its local extreme points, the points of level 1 ofgV,1(r) and other characteristics are computed by numerical integration. Furthermore, an asymptotically exact confidence interval for the intensity of nodes is obtained. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
