Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Here we introduce a new topological approach which provides a good model for the stability of linear and branched alkanes as well as the strain energy of cycloalkanes. We find that the ratio of 1,3-interactions with respect to the total number of 1,2-, 1,3- and 1,4-interactions plays a fundamental stabilizing role in the energetic of alkanes. These stabilizing effects are larger in branched than in linear alkanes. The heat of formation of alkanes can be obtained as a combination of stabilizing effects coming from atoms, bonds and protobranches.
