Internal Conversion and Photoprotection: Applications in Biochemistry

[@hks9899]

Really thanks sir, for give this knowledge.🙏

Ah you’re amazing! Thank you for this, as the frequency of the planet increases and these coronal mass ejections hit us, for me is detrimental to be in tune with these new frequencies and have as much exposure in order to not only affect my DNA structure, but also upgrade myself at a molecular level. You saved my brains so many brain cells. You’re a true blessing 🪄✨

Great~

it's great sir.i got a nice understanding .thank you so much

great video! Question @ 9:06 : so you mean heat energy being dissipated by molecules bumping into each other (phonons) .. because what most people understand of the term heat is IR-thermal radiation which would be photon emission. And how can it be that in vibrational relaxation the accelerated charges do no emit photons? I thought whenever you accelerate a charge, it automatically emits photons. And how does a molecule like melanin decide if it does internal conversion only by releasing heat and not decide to do fluorescence instead of internal conversion from S1 to S0? Thanks!!

[@nehasinghrajput2073]

On which factors internal conversion depends?

[@InquilineKea]

why are triplets lower energy? why is vibrational relaxation to adjacent energy levels always allowed?

[@Moon-cr4mu]

triplet states are more stable because of Hund's rules,

[@marwaa1729]

you mention that there is no emission on photons during internal conversion, but my textbook says otherwise. If what you say is true, when do you fluorescence and phosphorescence?

sorry master your video is titled "Internal Conversion" but you don't really explain what it is and what is its significance. here is my understanding for IC after reading IC of nucleus. In your plot you show two Energy states S1 and S2 do IC at the same energy level. The electrons although at the same energy levels have different Kinetic and Potential energies that's why they are called different S1 and S2. By IC while keeping total energy constant the KE and PE are different. an electron could be accelerated or decelerated doing IC.
