ChemicalBook provides the 1H NMR spectrum for trans-Cinnamic acid.

2015年2月5日 · In this present study, FT-IR, FT-Raman, 13 C NMR and 1 H NMR spectra for cinnamic acid have been recorded for the vibrational and spectroscopic analysis. The observed fundamental frequencies (IR and Raman) were assigned according to their distinctiveness region.

2008年1月12日 · Temperature stability and photodimerization kinetics of β-cinnamic acid and comparison to its α-polymorph as studied by solid-state NMR spectroscopy techniques and DFT calculations.

The view of the spectra can be scrolled around or scaled using the controls in the menu or by using the various mouse and keyboard shortcuts:

A: Mixture of [2- 2 H]cinnamic acid and unlabeled cinnamic acid. The broad signal of H-3 ( J H - 3 – D - 2 = 2 . 5 Hz not resolved) indicates the [2- 2 H]-isotopomer. The diminished...

2002年8月1日 · 1H NMR spectroscopy was used to follow the course of the photochemical conversion of methyl p-hydroxy-trans-cinnamate to the thermodynamically less stable cis isomer.

2001年9月12日 · We selected for a structural study using 13 C NMR spectroscopy (in solution and in the solid state, CPMAS) four cinnamic acids whose X-ray structures were known [1]: 1ap -methoxy (MXCINN) [2], 2ap -hydroxy (COUMAC01) [3], 3ap -methyl (JADVUF) [4] and 4ap -chloro (PCTCIN) [5].

2001年3月1日 · The present paper deals with the characterization of the polymorphs of cis -CA by vibrational and NMR spectra on the basis of the crystal structure and with the assignment of the solution spectra. The spectra of trans- cinnamic acid (trans -CA) (E -3-phenyl-2-propenoic acid) are also reported for comparison.

In this present study, FT-IR, FT-Raman, (13)C NMR and (1)H NMR spectra for cinnamic acid have been recorded for the vibrational and spectroscopic analysis. The observed fundamental frequencies (IR and Raman) were assigned according to their
