UV photodissociation spectroscopy of oxidized undecylenic acid films.
Oxidation of thin multilayered films of undecylenic (10-undecenoic) acid by gaseous ozone was investigated using a combination of spectroscopic and mass spectrometric techniques. The UV absorption spectrum of the oxidized undecylenic acid film is significantly red-shifted compared to that of the initial film. Photolysis of the oxidized film in the tropospheric actinic region (lambda > 295 nm) r...
متن کاملFungicidal PMMA-Undecylenic Acid Composites
Undecylenic acid (UA), known as antifungal agent, still cannot be used to efficiently modify commercial dental materials in such a way that this affects Candida. Actually, issues with Candida infections and fungal resistance compromise the use of Poly(methyl-methacrylate) (PMMA) as dental material. The challenge remains to turn PMMA into an antifugal material, which can ideally affect both sess...
متن کاملPhotodissociation spectroscopy of the Mg+-acetic acid complex.
We have studied the structure and photodissociation of Mg(+)-acetic acid clusters. Ab initio calculations suggest four relatively strongly bound ground state isomers for the [MgC(2)H(4)O(2)](+) complex. These isomers include the cis and trans forms of the Mg(+)-acetic acid association complex with Mg(+) bonded to the carbonyl O atom of acetic acid, the Mg(+)-acetic acid association complex with...
متن کاملInfrared photodissociation spectroscopy
The infrared photodissociation spectra of [(CO2)n(H2O)m] (n = 1–4, m = 1, 2) are measured in the 3000–3800 cm range. The [(CO2)n(H2O)1] spectra are characterized by a sharp band around 3570 cm except for n = 1; [(CO2)1(H2O)1] does not photodissociate in the spectral range studied. The [(CO2)n(H2O)2] (n = 1, 2) species have similar spectral features with a broad band at ≈3340 cm. A drastic chang...
متن کاملUndecylenic acid inhibits morphogenesis of Candida albicans.
Resilient liners are frequently used to treat denture stomatitis, a condition often associated with Candida albicans infections. Of 10 liners tested, 2 were found to inhibit the switch from the yeast form to hyphae and a third was found to stimulate this switch. The inhibitor was determined to be undecylenic acid.
