“…Recently, Bergmann and coworkers 5–7 proposed the stimulated Raman adiabatic passage (STIRAP) method, which is a very powerful technique to achieve the complete population transfer in molecular system. We applied this STIRAP method to the control of the proton motion of the intramolecular hydrogen bond 8–11 and the isomerization reaction 12 and showed the usefulness of this method. A number of generalizations of the STIRAP method, such as an adiabatic passage by light‐induced potentials (APLIP) 13, 14 and a Raman chirped adiabatic passage (RCAP) 15, 16, have been proposed to control the vibrational wavepacket.…”

Selective coronary angiography in severely dilated ascending aorta is technically challenging and sometimes impossible. The Terumo "five-in-six" system uses an extra long 5Fr guide catheter in a standard 6Fr guide catheter, so that the tip of the 5Fr guide catheter protrudes beyond the tip of the 6Fr catheter allowing an extra reach. This system has been used successfully to advance balloon catheters across chronic total occlusions (Takahashi et al, Catheter Cardiovasc Interv 2004;63:452-456) and stent delivery beyond proximal obstruction point (Mamas et al, Catheter Cardiovasc Interv 2008;71:358-363). We describe the successful use of this system in an atraumatic manner for selective coronary angiography in a patient with a severely dilated ascending aorta.

“…Laser control of double proton transfer (DPT) reactions has received less attention. Nishikawa et al [22] considered control of stepwise DPT in an asymmetrically substituted tetraflouro-porphyrin model using the stimulated Raman adiabatic passage (STIRAP) method. Assuming a stepwise transfer the description has been reduced to two independent one-dimensional potentials obtained from intrinsic reaction coordinate calculations.…”

Laser control of ultrafast double proton transfer is investigated for a twodimensional model system describing stepwise and concerted transfer pathways. The pulse design has been done by employing optimal control theory in combination with the multiconfiguration time-dependent Hartree wave packet propagation. The obtained laser fields correspond to multiple pumpdump pulse sequences. Special emphasis is paid to the relative importance of stepwise and concerted transfer pathways for the driven wave packet and its dependence on the parameters of the model Hamiltonian as well as on the propagation time. While stepwise transfer is dominating in all cases considered, for high barrier systems concerted transfer proceeding via tunneling can make a contribution.

Theoretical Study of Above-Threshold Dissociation on Diatomic Molecules by Using Nonresonant Intense Laser Pulses

et al. 2007

The above-threshold dissociation of the ground state of a OH molecule under intense nonresonant laser pulses has been studied using the time-dependent Schrödinger equation with discrete variable representation. The applied field is assumed as a two-color mixed nonresonant laser pulses which has the nonresonant frequency omega and the overtone 2omega. After modulating the relative phase factor between the omega and 2omega pulse, we extracted a three-photon absorption peak or a five-photon absorption peak in the ATD spectrum.
