The Chemistry of Excited States
... Because molecules can have many occupied and empty molecular orbitals, there can be many possible transitions to promote an electron from a low-energy occupied to higher-energy empty orbital. However, only a few of these molecular orbitals are involved in absorption of light and the formation of exc ...

... is, logarithmically) averaged over the phases. This leads to a transmittance that is simply the product of the transmittances of the individual elements, so that the effect of multiple reflections on the transmitted light cancels by destructive interference. The light intensity decays exponentially ...

Di raction and Interference PRECAUTION
... This experiment is greatly facilitated by the use of a laser as a light source. The laser light is highly monochromatic and coherent. Coherence means that there are surfaces, in this experiment approximately planes, in which the light is in phase. When such light falls on a ~ oscillates in phase ove ...

The rotational spectrum consists of approximately equally spaced rotational absorption lines spaced about 110 GHz apart. The isotopes like CO18 have very similar spectra. There will be a homework problem on thi ...

Discovery Of A Magnetic Field In The O9 Sub-Giant Star HD
... The longitudinal magnetic field (B ) was inferred from each LSD Stokes V profile in the manner described by Silvester et al. (2009). The longitudinal field measurements, which are reported in Table 1, vary between −167 G and +282 G, with a typical uncertainty of 20–40 G. While the longitudinal fie ...
