Near-IR photodissociation of peroxy acetyl nitrate [PDF]
Atmospheric Chemistry and Physics, 2005 Measurements of the C-H overtone transition strengths combined with estimates of the photodissociation cross sections for these transitions suggest that near-IR photodissociation of peroxy acetyl nitrate (PAN) is less significant (Jnear-IR≈3x10-8s ...

(3+1)D Printing of Core–Clad Waveguide by Two‐Photon Polymerization
Advanced Materials Technologies, Volume 10, Issue 15, August 7, 2025.Low‐loss, single‐mode core–clad optical waveguides are fabricated using a novel (3+1)D multiphoton polymerization technique in a hybrid resin. Precise laser power control and multi‐pass exposure enable refractive index engineering and reduce scattering. Raman spectroscopy confirms the correlation between polymerization and index change.

Photodissociation of HBr/LiF(001): A quantum mechanical model [PDF]
The photodissociation dynamics of HBr adsorbed on a LiF(001) surface is studied using time-independent quantum mechanics. The photodissociation lineshape and the Br(P(sub 1/2)-2)/Br(P(sub 3/2)-2) yield ratio are computed and compared with the ...

Dissociation Dynamics of CIONO_2 and Relative Cl and ClO Product Yields following Photoexcitation at 308 nm [PDF]
, 1995 Chlorine nitrate photolysis at 308 nm has been investigated with a molecular beam technique. Two primary decomposition pathways, leading to Cl + NO_3 and ClO + NO_2, were observed.

Photodissociation of p-process nuclei studied by bremsstrahlung induced activation
, 2005 A research program has been started to study experimentally the near-threshold photodissociation of nuclides in the chain of cosmic heavy element production with bremsstrahlung from the ELBE accelerator. An important prerequisite for such studies is good

Charge-transfer photodissociation of adsorbed molecules via electron image states
, 2007 The 248nm and 193nm photodissociation of submonolayer quantities of CH$_3$Br and CH$_3$I adsorbed on thin layers of n-hexane indicate that the dissociation is caused by dissociative electron attachment from sub-vacuum level photoelectrons created in the ...
