摘要

在雙三角錐形之錯化物L-Fe(CO)_4（L表順丁烯二酸，反丁烯二酸及順丁烯二酸酐）中，配位基L是位在三角平面的位置。這些錯化物在紅外線光譜中顯示出四個CO吸收頻率，利用C_(2v)局部對稱性，對此四個頻率可作一合理之指稱且計算出相關之力常數及相互作用常數。

並列摘要

In trigonal-bipyramidal complexes L-Fe(CO)_4 (L: maleic acid, fumaric acid, and maleic anhydride.), the ligand L lies in the equatorial position. These complexes exhibit four CO stretching bands in their IR spectra. Using a C_(2v). local symmetry, a reasonable assignment of these bands is made and accordingly, the relavent force constants and interaction constants are calculated.
