| Molecular Conformation and Structural Correlations of Liquid D-terf-Butanol at Room Temperature by Neutron Diffraction  | | | | Abstract
| An analysis o f neutron diffraction data o f liquid deuterated terr-butanol at room temperature to determine its molecular conformation is presented. Being a big molecule o f 15 sites, the analysis is tricky and needs careful consideration. The resulting molecular parameters are compared with those obtained from other experimental data analysis and model calculations. The information about the intermolecular structural correlations, hydrogen-bonded molecular association in partcular is also obtained from the diffraction data analysis. -PACS number: 61.25 | | | |

| Phenolic Compounds as a Tool of Bioindication for Novel Forest Decline at Numerous Spruce Tree Sites in Germany | | | | Abstract
| Within a project that applied biochemical criteria to the diagnosis of damage to Norway spruce, 43 sites in western and eastern Germany showing only moderate tree damage were screened for the amounts of methanol soluble phenolic compounds in spruce needles. The concentrations of most of the main compounds -especially catechin -positively correlated with needle loss and the altitude of the site. It was also found that it is necessary to differenti ate between trees younger and older than 60 years of age. The correlations between the increase of the phenolic compounds studied and the needle loss or the damage class are stronger in the younger trees, possibly implicating differences in metabolic state or distur bances in protectective mechanisms in the older trees. | | | |
