Phys. Rev. A 77, 054502 (2008) [4 pages]Infrared frequency standard using electrically trapped moleculesReceived 11 March 2008; published 28 May 2008 This paper discusses the possibility of developing a frequency standard using molecular vibrational transition frequencies, which are useful in optical communications. Cold molecules (<300 μK) are trapped by microwave or infrared laser light, whose frequency is chosen so that the Stark shift on the transition frequency is significantly reduced. Microwave trapping is much more advantageous than infrared trapping for measuring the vibrational transition frequency to within an uncertainty of 10−11. © 2008 The American Physical Society URL:
