The amphiphiles 1-octadecanol (octadecyl (stearyl) alcohol, ODA) and 1,2-dioleoylglycerol (DOG) were studied by IR spectroscopy and X-ray diffraction combined with multiscale theoretical modeling. The computations allowed us to rationalize the experi

The infrared spectra of primary alkylamines largely belong to one of two different types as found out by a systematic data search. This search was motivated by observing before an intriguing spectral pattern (type-I) in our studies of octadecylamine,

The conformation of nucleic acids can be probed reliably by the geometrical arrangement of the PO2- groups in the backbone. The phosphate arrangement is described by two angles, θOO and θOPO, which can be determined by several methods. In the prese

The chemical characteristics of the polar parts of phospholipids as the main components of biological membranes were investigated by using infrared (IR) spectroscopy and theoretical calculations with water as a probe molecule. The logical key molecul

Lipids as an important class of chemical and, in particular, biochemical compounds have been largely characterised by a number of structural and thermodynamic methods in the past. An in-depth application of vibrational spectroscopy as one of the powe

Lipids with phytanyl or phytanoyl chains are of basic interest because of their natural occurrence in the membranes of extremophilic archaebacteria and frequent use in biochemical studies and applications as a model for stable bilayers. Since data fr

Hydration is an important factor in regulating the phase behaviour of lipids and besides affects their interactions with other compounds relevant for biological membranes. We present a reliable and fast method to detect and characterise hydration-ind

The polar headgroups are an important molecular subregion of phospholipids since they mediate a substantial part of the interactions emerging with other constituents of biological membranes, be it inherent macromolecules (proteins) or water as formin

Phospholipids — as biomembrane constituents — are an interesting class of molecules, and among them, phosphatidylcholines (PCs) or lecithins are most abundant in eucaryotic organisms. We have used FTIR spectroscopy to explore hydration-induced ph
