In a variety of fields including chemistry and biology, crown ethers are the prototypical model. Two of the most common crown ethers are 12 crown 4 (12c4) and 18 crown 6 (18c6). We have used infrared spectroscopy to study the microsolvation of the K$^+$(12c4)(H$_2$O)$_n$ and K$^+$(18c6)(H$_2$O)$_n$ systems for n=1-4 in the O$-$H stretching region of water. Additionally, we will present new studies where these complexes have been tagged with argon. Since the argon-tagged complexes are colder than their untagged counterparts, we can consider the effect of temperature in these systems. These spectroscopic studies, combined with $\it{ab}$ $\it{initio}$ calculations, can be used to characterize the competing non-covalent interactions, and thus understand the molecular basis behind the selectivity exhibited in the condensed phase. en_US dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title INFRARED STUDIES AND TEMPERATURE EFFECTS OF HYDRATED POTASSIUM$-$CROWN ETHER SYSTEMS en_US dc.type Article en_US
