Why does a compound in the excited triplet state undergo intersystem crossing before returning to the ground state?
it actually does not. intersystem crossing is what creates the triple state not what reduces it to its ground state. it happens in a series of steps... first you have the excited singlet state created by photon absorption which would generally immediately emit flouresence to return to the ground state. however, if it does not emit flouresence than it becomes subject to intersystem crossing (ISC). ISC can cause an electron to invert its rotation and begin the same orbital rotation path of another electron, therefore creating the triplet state (two electrons having same directional orbit). the triplet state then undergoes internal conversion, again altering those two electrons in question. Now, when the triplet is reduced to the ground state it emits phosphorescence instead of flourescence.

How long will an electron stay in the excited state?
The time an electron stays in an excited state can vary depending on the specific electron transition and energy level involved. In general, electrons can stay in an excited state for fractions of a second to several hours before returning to a lower energy level by emitting a photon of light.
What compound in plants makes photosynthesis possible?
Chlorophyll is the compound in plants that makes photosynthesis possible. It has a unique structure that allows it to lose electrons easily when it gets excited by energy. This is where the conversion from light energy to chemical energy begins.
What can a flame test tell you about a certain compound?
No, because non metal atoms do not enter an excited state.
Do you say excited to or excited about an upcoming event?
You can say either "excited to" or "excited about" an upcoming event, as both are commonly used and grammatically correct. It just depends on your personal preference.
What lanthanide forms a compound that allows you to see red on a computer screen?
The lanthanide element that is used in the compound creating red color on a computer screen is europium. It is used as a phosphor material in the red pixels of a screen to emit red light when excited by electrons.

Will the little couple be returning in 2012?
Yes. They have been filming additional seasons, and fans are waiting with excited anticipation for Bill and Jen's next adventures.
Is anyone else excited about Toonami returning on saturday nights?
Perhaps I would be if they included more than just Deadman Wonderland and Casshern Sins.
How was Columbus crew were they excited or what?
Yes they were. First because they had survived the ocean crossing, and secondly because they thought they had found South East Asia.
How are electrons become excited?
Electrons become excited when they absorb energy, such as through exposure to light or heat. This additional energy causes the electrons to move to a higher energy level, creating an excited state. The electrons will eventually release this energy by returning to their original, lower energy state, emitting light or heat in the process.
What is the compound subject in the following sentence The game both entertained and excited the baseball fans?
game and baseball fans
When a molecule absorbs a photon one of the electron is raised in what state?
When a molecule absorbs a photon, an electron is raised from its ground state to an excited state. This leads to an increase in the electron's energy level, causing the molecule to become temporarily unstable before returning back to its ground state through various relaxation processes.
How long will an electron stay in the excited state?
The time an electron stays in an excited state can vary depending on the specific electron transition and energy level involved. In general, electrons can stay in an excited state for fractions of a second to several hours before returning to a lower energy level by emitting a photon of light.
What term refers to the massive increase in population after World War 2?
Baby Boomers The result of hundreds of thousands of lonely/excited servicemen returning home from a long war.
Why did each compound produce a flame of a different color?
Different elements have different emission spectra, meaning that if the electrons in an atom are excited, they will release that energy in different color of light. The flame color depends on the elements in the compound.
