Effect of molecular structural isomers in thermal lens spectroscopy

Article history: Received 7 March 2014 In final form 31 March 2014 Available online 5 April 2014 We explore the importance of molecular structure on thermal lens (TL) spectroscopy by measuring the effects of molecular isomerization on TL measurements. In particular, we present a case study for all the structural isomers of butanol, namely, normal-butanol (n-BuOH), secondary-butanol (s-BuOH), is...

Probing actin polymerization by intermolecular cross-linking

We have used N,N'-1,4-phenylenebismaleimide, a bifunctional sulfhydryl cross-linking reagent, to probe the oligomeric state of actin during the early stages of its polymerization into filaments. We document that one of the first steps in the polymerization of globular monomeric actin (G-actin) under a wide variety of ionic conditions is the dimerization of a significant fraction of the G-actin ...

Probing intermolecular couplings in liquid water with two-dimensional infrared photon echo spectroscopy.

Two-dimensional infrared photon echo and pump probe studies of the OH stretch vibration provide a sensitive probe of the correlations and couplings in the hydrogen bond network of liquid water. The nonlinear response is simulated using numerical integration of the Schrodinger equation with a Hamiltonian constructed to explicitly treat intermolecular coupling and nonadiabatic effects in the high...

Contributions of transient absorption and population lens in thermal lens spectroscopy

Contaminations of the population lens and transient absorption in thc obsened thermal lens signal sometimes cause a misinterpretation of the signal. Rcccntly, we ha1.c developed several methods to evaluate the relative contributions of these components in thc observed thermal lens signal. These methods with reccnt results are sumtnarizcd, and mcrits and limitations of each method are discussed.
