Whereas the Raman frequency shifts of the most frequently investigated bands of C-C and C-H stretching regions only indicate the main phase transition (P(beta')-L(alpha)) of the pure DPPC/water system, the Raman shift of C-H scissoring vibration at 1440 cm(-1) was found to be able to reveal the pretransition (L(beta')-P(beta')) as well. Analyzing the spectral parameters of the trans band at 1128 cm(-1), which does not overlap with DCP vibrational modes, a continuous decrease of trans conformations was found with increasing DCP concentration at 26 degrees C accompanying the phase transitions L(beta')-P(beta') and P(beta')-L(alpha). The intensity ratio of the symmetrical and asymmetrical methylene stretching bands (at 2850 cm(-1) and 2880 cm(-1)), defined as the disorder parameter by Levin [Levin, I.W., 1985. Two types of hydrocarbon chain interdigitation in sphingomielin bilayers. Biochemistry 24, 6282-6286], indicated that in the interdigitated phase (L(I)) the order is markedly high and comparable with that of L(beta). Both the phase transition P(beta')-L(alpha) in the DCP/DPPC molar ratio range of 10/100-50/100 and the phase transition L(I)-L(alpha) led to a significant increase of disordered chains and the presence of DCP molecules induced a more disordered chain region than that observed in the L(alpha) phase of DPPC. Nevertheless, it was found that the L(alpha) phase with DCP contains approximately the same amount of trans conformers than that without DCP. 000050645 536__ $$0G:(DE-Juel1)FUEK407$$2G:(DE-HGF)$$aTerrestrische Umwelt$$cP24$$x0 000050645 536__ $$0G:(DE-Juel1)FUEK414$$aKondensierte Materie$$cP54$$x1 000050645 588__ $$aDataset connected to Web of Science, Pubmed 000050645 65320 $$2Author$$aDPPC liposomes 000050645 65320 $$2Author$$aphase transitions 000050645 65320 $$2Author$$aFF-Raman spectroscopy 000050645 65320 $$2Author$$a2.4-dichlorophenol 000050645 650_2 $$2MeSH$$a1,2-Dipalmitoylphosphatidylcholine: chemistry 000050645 650_2 $$2MeSH$$aChemistry, Physical 000050645 650_2 $$2MeSH$$aChlorophenols: chemistry 000050645 650_2 $$2MeSH$$aMembranes, Artificial 000050645 650_2 $$2MeSH$$aPhase Transition 000050645 650_2 $$2MeSH$$aPhysicochemical Phenomena 000050645 650_2 $$2MeSH$$aSensitivity and Specificity 000050645 650_2 $$2MeSH$$aSpectrum Analysis, Raman: methods 000050645 650_2 $$2MeSH$$aTemperature 000050645 650_7 $$00$$2NLM Chemicals$$aChlorophenols 000050645 650_7 $$00$$2NLM Chemicals$$aMembranes, Artificial 000050645 650_7 $$0120-83-2$$2NLM Chemicals$$a2,4-dichlorophenol 000050645 650_7 $$02644-64-6$$2NLM Chemicals$$a1,2-Dipalmitoylphosphatidylcholine 000050645 650_7 $$2WoSType$$aJ 000050645 7001_ $$0P:(DE-Juel1)VDB793$$aKoglin, E.$$b1$$uFZJ 000050645 7001_ $$0P:(DE-HGF)0$$aMeier, R.$$b2 000050645 7001_ $$0P:(DE-Juel1)129484$$aKlumpp, E.$$b3$$uFZJ 000050645 773__ $$0PERI:(DE-600)1496839-3$$a10.1016/j.chemphyslip.2005.11.005$$gVol. 139, p. 115 - 124$$p115 - 124$$q139<115 - 124$$tChemistry and physics of lipids$$v139$$x0009-3084$$y2006 000050645 8567_ $$uhttp://dx.doi.org/10.1016/j.chemphyslip.2005.11.005 000050645 909CO $$ooai:juser.fz-juelich.de:50645$$pVDB 000050645 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000050645 9141_ $$y2006 000050645 9131_ $$0G:(DE-Juel1)FUEK407$$bErde und Umwelt$$kP24$$lTerrestrische Umwelt$$vTerrestrische Umwelt$$x0 000050645 9131_ $$0G:(DE-Juel1)FUEK414$$bMaterie$$kP54$$lKondensierte Materie$$vKondensierte Materie$$x1$$zentfällt bis 2009 000050645 9201_ $$0I:(DE-Juel1)VDB50$$d31.12.2006$$gICG$$kICG-IV$$lAgrosphäre$$x0 000050645 9201_ $$0I:(DE-Juel1)VDB421$$d31.12.2006$$gISG$$kISG-4$$lBiologische Schichten$$x1 000050645 970__ $$aVDB:(DE-Juel1)79177 000050645 980__ $$aVDB 000050645 980__ $$aConvertedRecord 000050645 980__ $$ajournal 000050645 980__ $$aI:(DE-Juel1)IBG-3-20101118 000050645 980__ $$aI:(DE-Juel1)ICS-7-20110106 000050645 980__ $$aUNRESTRICTED 000050645 981__ $$aI:(DE-Juel1)IBI-2-20200312 000050645 981__ $$aI:(DE-Juel1)IBG-3-20101118 000050645 981__ $$aI:(DE-Juel1)ICS-7-20110106
