Using a homemade ultrasensitive space charge limited ion detector, the K 2 singlet gerade states (7-9 1 S / g and 4 1 P g ) were observed for the first time. The exotic potential of the double minimum 7 1 S / g state was constructed using a hybrid approximation method. The molecular constants and th

✦ Synopsis
The Rydberg-Klein-Rees potential curve of the 3 1 P g state which covers the internuclear distance from 3.59926 to 6.76571 A ˚is constructed from the experimentally determined B £ and G(£) values. The predicted exotic shape (change in slope outside Ç5.7 A ˚) agrees with the experimental results. The dissociation energy of this state which dissociates to the K(4s) / K(5p) atomic asymptotic limit is determined to be 2731.292 { 0.085 cm 01 .

Optical-optical double resonance spectroscopy was used to study the 1 g ( 3 P 1 ) ion-pair state of I 2 correlating to I -( 1 S) + I + ( 3 P 1 ) at the dissociation limit. We gained access to the 1 g ( 3 P 1 ) state though the A 3 (1 u ) state in the (1 + 1) photon-excitation scheme. The pump laser
The \(0_{g}^{+}\left({ }^{1} D\right)\) ion-pair state of \(\mathrm{I}_{2}\) has been analyzed by optical-optical double-resonance using the \(0_{g}^{+}\left({ }^{1} D\right)-B^{3} \Pi\left(0_{u}^{+}\right)-X^{1} \Sigma_{g}^{+}\)photoexcitation sequence.
