  • Difference between an absorbance, emission, and excitation spectrum for . . .
    The excitation spectrum shows at what wavelengths the solution uses to produce its fluorescence The emission spectrum shows what wavelengths are given off from the solution For absorbency spectrum, the solution has all the wavelengths shining on the solution, and you monitor the wavelengths of interest
  • De-excitation of a molecule - Chemistry Stack Exchange
    To this, the lecturer replied that perhaps, there is de-excitation of the electrons through other pathways, such as through molecular vibrations (i e kinetic energy of the molecules) However, he also was not so sure about the matter Thus, I would like to seek clarification on how these excited electrons de-excite after initial excitation
  • orbitals - Excitation of electron in Niels Bohrs atomic model . . .
    However, such an excitation implies a transition between possible states of the atom It is necessary that the energy of the photon match the difference in energy of the atomic states In the case where the two states are bound (if an electron is not excited into the continuum of ionized free states) the result is that only a subset of photon energies can be absorbed by the atom
  • what is the difference between excitation and emission spectroscopy . . .
    In EXCITATION spectroscopy the Mex scans in a wavelength range equal to that used in absorption spectroscopy The Mem is fixed at a certain wavelength What you want to have is a spectrum (excitation) that is proportional to the absorption spectrum
  • Lécher le pipi de ma femme - Fantasmes - FORUM sexualité
    L'excitation sur les plaisirs liés à l'uro est très rependu mais par contre ca reste une pratique confidentielle Braver l'interdit, gouter à de l'intime sont est une forme de plaisir qui ne laisse pas insensible Ma femme est comme la tienne, ca ne l'intéresse pas mais elle y prend pourtant un furieux plaisir
  • organic chemistry - Excited states: S0, S1, S2 interpretation . . .
    This seemed especially accurate to me when studying the excitation of ethanal, where the S₁ state corresponds to the transition from HOMO to LUMO However, when I worked with a more complex molecule and performed an excitation calculation using Time-Dependent Density Functional Theory (TDDFT) for the first ten excited states (S₁, S₂,
  • éjaculation sans érection - Troubles de lérection - FORUM Santé
    les couilles fonctionnent jour et nuit sans arrêt comme le coeur ou l'estomac sitôt vides les réservoirs commencent à se remplir, et l'excitation psychologique monte de plus en plus les couilles ont besoin de se vider par tous les moyens possibles, et surtout les plus expéditifs
  • physical chemistry - Calculating excitation energies of a molecule . . .
    I am trying to calculate the excitation energies for the first three transitions of a molecule which is made up by a chain of k phenyl rings, where k shall be between 1 and 8 The angle between each rings shall be $\pm 30^\circ$
  • computational chemistry - Which is most reliable excitation energy . . .
    I like to point out to my group that optical excitations consist of two things consistently (e g , in a UV Vis spectra) There are the excitation energies (the x-axis) and the intensity or extinction coefficient (the y-axis) To some degree, the peak widths give a bit more information (e g , into vibrational structure)
