The simultaneous FT-Raman–differential scanning calorimetry (SRD) technique is described, which allows FT-Raman spectra to be collected from thermally sensitive samples with a very low power density at the sample surface, immediately followed by an in situ DSC melting curve. This gives unambiguous characterisation of samples which are thermally sensitive or which could be structurally transformed by an incident high power density laser beam. In the current work, SRD has been applied to a study of the structural polymorphs of the triglyceride 1,3-distearoyl-2-oleoylglycerol (SOS). SRD analysis shows DSC heating curves with onset melting points and features identifying the polymorphs produced as α, γ, β′, β2 and β1, conforming well to literature thermal behaviour. Interpretation of the corresponding Raman spectra for these polymorphs provides confirmation of existing structural models in the literature based on other analytical techniques.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
