TL;DR: The structures of the trichoaurantianolides B (2), C (3) and D (4) isolated from the fruiting bodies of Tricholoma aurantium have been elucidated by manifold spectroscopic studies and confirmed by X-ray crystallographic analysis as discussed by the authors.

TL;DR: EHMO calculations applied to fractional coordinates of the Zn(macm)2(NH3)2 complex indicate that the atomic orbitals of theZn do not contribute to HOMO and LUMO of the complex.

TL;DR: In this article, both univariate (histogram representation, HR) and multivariate (cluster analysis, CA, and principal-component analysis, PCA) statistical techniques are presented and applied to structure correlation problems.
Abstract: Novel statistical and numerical methods of data analysis, which make extensive use of the estimated errors (e.s.d.'s) of the data are presented and applied to structure-correlation problems. The novel procedures concern both univariate (histogram representation, HR) and multivariate (cluster analysis, CA, and principal-component analysis, PCA) statistical techniques. In the case of HR, the problem of optimally selecting the dimensions of the spaces is bypassed by convoluting a series of normal functions. In the case of CA, a probability significance is given to the similarity between two (or more than two) objects. In the case of PCA, a cross-validation technique, which takes into account the e.s.d.'s of the row data, allows the determination of the dimensionality of the principal-component space, easy detection of outliers with respect to any principal component, and evaluation of a more comprehensive percentage of the variance described by the principal components.

Abstract: The structures of the new diterpene lactones trichoaurantianolides B (2), C (3) and D (4), isolated from the fruiting bodies of Tricholoma aurantium have been elucidated by manifold spectroscopic studies and, in the case of 2, confirmed by X-ray crystallographic analysis.
