The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) Chemical intermediates Molecules in excited states Biological molecules Polymers.The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: Infrared spectroscopy (mid, far, near) Raman spectroscopy and non-linear Raman methods (CARS, etc.) Electronic absorption spectroscopy Optical rotatory dispersion and circular dichroism Fluorescence and phosphorescence techniques Electron spectroscopies (PES, XPS), EXAFS, etc. Microwave spectroscopy Electron diffraction NMR and ESR spectroscopies Mssbauer spectroscopy X-ray crystallography Charge Density Analyses Computational Studies (supplementing experimental methods)We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
