Special Issue Information

Dear Colleagues,

Coordination compounds and supramolecular complexes have been the focus of research for many years because of their wide range of applications. These systems can be studied by various spectroscopic techniques, including UV–Vis spectroscopy, spectrofluorimetry, and vibrational spectroscopy. Different spectroscopic methods and their combinations are used for the non-invasive study of molecular systems to investigate their structure, properties, and dynamics in different environments and under different physico-chemical conditions.

The focus of this Special Issue is on the application of spectroscopic and spectrometric techniques to the study of various molecular systems, including metal and supramolecular complexes. We invite the submission of original or review articles to this Special Issue covering numerous research areas, such as structure determination of complexes in the solid state and in solution, determination of reaction mechanisms, phase solubility measurements, ion–molecule interactions, etc.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Spectroscopy Journal is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Etherified cellulose derivatives, in contrast to cellulose, are soluble in water at room temperature and have a wide variety of applications. One of their most important characteristics is their decrease in solubility with temperature. The objective of this work was to study the rotational isomerism of the side chains of hydroxypropyl cellulose (HPC) in aqueous solution as sole solute and in the presence of chloride, sulfate, and barium ions as a function of temperature. Infrared Attenuated Total Reflectance spectroscopy was used to measure changes in the side-chain rotational isomerism using the structurally sensitive methylene wagging region as the probe. Decreases in end-gauche and kink conformers were observed. Principal component analysis revealed the presence of multiple forms of HPC at higher molecular weight. The precipitation of HPC as the temperature was increased was accompanied by a reduction in the numbers of end-gauche and kink conformers. Full article
