In an octahedral complex, the ligands bond along the x , y , and z axes. The energy of the and orbitals is not raised as much. Br , Cl , F , and I . Br Cl F largest 4. They contain valence electrons with relatively low excitation energy.
Derivative spectroscopy allows overlapping peaks in a spectrum to be distinguished from each other.
It makes peaks more apparent and allows for more precise peak assignments. List two processes which compete with fluorescence of an excited state molecule. Describe the two types of fluorescence spectra that may be gathered. In absorption, is measured. Increasing doesn't change this ratio much.
