1,3-Cyclohexanedione is an organic compound with the formula (CH 2) 4 (CO) 2. It is one of three isomeric cyclohexanediones. It is a colorless compound that occurs naturally. It is the substrate for cyclohexanedione hydrolase. The compound exists mainly as the enol tautomer. [2]
A [1,5] shift involves the shift of 1 substituent (hydride, alkyl, or aryl) down 5 atoms of a π system. Hydrogen has been shown to shift in both cyclic and open-chain compounds at temperatures at or above 200 ˚C. [4] These reactions are predicted to proceed suprafacially, via a Hückel-topology transition state. [1,5] hydride shift in a ...
Resonance ionization is a process in optical physics used to excite a specific atom (or molecule) beyond its ionization potential to form an ion using a beam of photons irradiated from a pulsed laser light. [1] In resonance ionization, the absorption or emission properties of the emitted photons are not considered, rather only the resulting ...
Dimedone is an organic compound with the formula (CH 3) 2 C(CH 2) 2 (CO) 2 (CH 2). Classified as a cyclic diketone, it is a derivative of 1,3-cyclohexanedione. It is a white solid that is soluble in water, as well as ethanol and methanol. It once was used as a reagent to test for the aldehyde functional group.

Time evolution of state populations for counter-intuitive STIRAP pulse sequence demonstrating coherent transfer. In quantum optics, stimulated Raman adiabatic passage (STIRAP) is a process that permits transfer of a population between two applicable quantum states via at least two coherent electromagnetic (light) pulses.
1952: Li and Jasper applied the Renshaw, Forbes, & Morrison method to study electrical activity in the cerebral cortex of a cat. [14] Hodgkin–Huxley model was revealed, where they used a squid giant axon to determine the exact mechanism of action potentials. [15] 1953: Iridium microelectrodes developed for recording. [16]
