• Abstracts should be 300 words or less.
• You may use Microsoft Word or Text format. Keep the same point size throughout.
• Left justify everything. Do not use extra returns.
• If using Word, please use superscript, subscript, italics, bold and underline where appropriate.
• Use upper and lower case lettering throughout. Do not use all caps unless it is to identify a trade name, registered name or other name that mandates all caps. In the title of the paper be sure to capitalize the first letter of each word as needed.
• Leave a space between the header information and abstract proper.
• Leave a space between the abstract proper and the information we need to communicate with you
• Keep the abstract text in one paragraph. If literature citations are needed, insert them in parentheses and not as footnotes. Credits, if any, should be added at the end of the abstract, but not as a new paragraph.
• If structures or other forms of illustrations are used, drawings should be part of the overall abstract.

Multi-Frequency EPR Analysis of Dipolar and Exchange Interactions Between Managese and Tyrosine In The S₂ Y_z State of Photosystems II. K.V.

Acetate-inhibited photosystem II, upon room temperature illumination, exhibits a 240 G wide X-band EPR signal at 10 K.¹ This EPR signal arises from an interaction between the S₂ state of the Mn₄ cluster and an oxidized tyrosine residue, Y_z.² In the present study, the exchange and dipolar interactions between the two paramagnetic species are simulated at X and Q-band frequencies utilizing second-order perturbation theory.³ The positions and relative intensities of the hyperfine lines in the S = ½ S₂ -state multiline EPR signal are accurately simulated by including g-anisotropy and four sets of axially symmetric ⁵⁵Mn hyperfine tensors. These parameters are then used to simulate the dipolar and exchange interactions giving rise to the broad experimental S₂ Y_z EPR signal at X and Q-band frequencies. A precise distance determination between the Mn₄ Cluster and Y_z in the O2-evolving complex better enables us to elucidate the direct involvement of Y_z in water-oxidation chemistry.
