Panjang gelombang radiasi elektro m

Panjang gelombang radiasi elektro magnetik ultra violet dan sinar tampak jauh lebih pendek dari pada infra merah, yaitu untuk ultra violet 100 – 400 nm dan sinar tampak 400 – 750 nm. Absorpsi radiasi ultra violet atau sinar tampak akan mengakibatkan terjadinya transisi elektronik. Promosi elektron-elektron dari orbital dasar berenergi rendah, ke orbital keadaan tereksitasi dengan energi yang lebih tinggi. Panjang gelombang radiasi ultra violet atau sinar tampak tergantung pada mudahnya promosi elektron. Molekul yang memerlukan lebih banyak energi untuk promosi elektronnya akan menyerap pada panjang gelombang yang lebih pendek. Molekul yang memerlukan lebih sedikit energi untuk promosi elektronnya, akan menyerap pada panjang gelombang yang lebih panjang. Senyawa yang menyerap cahaya dalam daerah tampak (senyawa berwarna) mempunyai elektron yang lebih mudah dipromosikan (energi lebih rendah) dari pada senyawa yang menyerap pada panjang gelombang ultra violet yang lebih pendek.

Electro magnetic radiation wavelength ultraviolet rays and seem much shorter than infrared, namely ultra violet for 100 – 400 nm and the rays seem 400 – 750 nm. Ultra violet radiation absorption or x-ray look will result in the occurrence of electronic transitions. Promotion of the orbital electrons of low energy basis, to the excited state orbitals with higher energy. The wavelength of radiation ultra violet rays appear to depend on the electron promotion easy. Molecules require more energy for the promotion of its electrons will absorb at wavelengths which are shorter. Molecules that require less energy to the promotion of its electrons, it will absorb at wavelengths that are longer. Compounds that absorb light in the visible area (colored compounds) have electrons that are more easily promoted (lower energy) than compounds that absorb ultraviolet at a wavelength shorter.

Electro-magnetic radiation wavelength ultraviolet and visible light is much shorter than in the infrared, which is to ultra violet 100-400 nm and visible light 400-750 nm. The absorption of ultraviolet radiation or visible light will cause the electronic transition. Promotion of electrons from basic low-energy orbital, orbital into an excited state with higher energy. Long-wave ultraviolet radiation or visible light depends on the ease of electron promotion. Molecules which require more energy to the promotion of electrons will absorb at shorter wavelengths. Molecules which requires less energy for electron promotion, will absorb at longer wavelengths. Compounds that absorb light in the visible region (colored compound) has promoted electron easier (lower energy) than the compound that absorbs the ultraviolet wavelengths shorter.
