Vibrational Partition Functions from Bond Order and Populations Relationships
ChemPhysChem, EarlyView.A new computational model is presented that predicts vibrational partition functions using bond orders and populations relationships (QBOP). This model demonstrates that thermochemical energy contributions can be reasonably approximated based on well‐conditioned orbital populations without the need for a costly Hessian calculation.

From Turpentine to (‐)‐Menthol: a New Approach
ChemSusChem, Accepted Article.The rising popularity of (‐)‐menthol, as the main component of the natural mint aroma with applications in the pharmaceuticals, cosmetics and food industry, leads to a growing need for synthetic menthol production to satisfy the world demand. In this study a novel green synthesis route for menthol is presented.
