Potassium Iodide | KI or IK | CID 4875 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
Potassium iodide (KI) is prepared by reacting potassium hydroxide to iodine with a hot solution. It is used mainly in the form of a saturated solution, 100 g potassium iodide to 100 ml water. That equates to around 50 mg/drop.
1: Absorption cross sections Davidovits and Brodhead, 1967.A preliminary measurement of the photodissociation product anisotropy by photofragment spectroscopy at 28800 cm-1 Ormerod, Powers, et al., 1974 indicates strong contributions from perpendicular transitions.: 2: Photodissociation produces K(4p 2 P); similarly, photodissociation at 52600 cm-1 leads to K(5p 2 P) Earl and Herm, 1974.
The analysis of K-off-I differential elastic scattering measurements Kaufmann, Lawter, et al., 1974 suggests that only 0 + (D e ~ 150 cm -1, r e ~ 3.85 Å) is favorably situated for transitions from the ground state.
