This study is a survey of the effects on the chemical shift of the olefinic protons of cinnamic acids and some other styrenes when various substituents are present. Cinnamic acids were chosen as the model compounds because they are easily synthesized, handled, and purified. Compared to many of the other olefinic compounds, they give simple and uncomplicated spectra. They also provide applications of many of the basic principles that regulate the chemical shift. All of the types of shielding are found in these compounds, caused either by the ring or the substituents on the ring. Effects of stereochemistry can be seen on the ortho substituted compounds, such as in the ciscinnamic acids.
