How Do You Spell SINGLET OXYGEN?

Pronunciation: [sˈɪŋɡlət ˈɒksɪd͡ʒən] (IPA)

Singlet oxygen is a high-energy form of molecular oxygen that plays a crucial role in various chemical reactions. Its spelling is determined by its pronunciation, which can be represented in the International Phonetic Alphabet as /ˈsɪŋɡlɛt ˈɒksɪdʒən/. The word is pronounced with stress on the first syllable, followed by the sound of "ng" in "sing," and then the short "e" sound in "let." The second word is pronounced with the short "o" sound in "not," and then the "k-s" cluster followed by the "zh" sound in "vision."

SINGLET OXYGEN Meaning and Definition

1. Singlet oxygen refers to a highly reactive form of molecular oxygen, also known as ^1O2 or singlet delta oxygen, which exists in an electronically excited state. Unlike normal molecular oxygen (O2), which has a ground state in which the two oxygen atoms are joined by a stable double bond, singlet oxygen has unpaired electrons in its outer shell, making it highly reactive and unstable.

   Singlet oxygen can be formed through various chemical reactions involving molecular oxygen, such as photosensitization processes or energy transfer reactions. It can also be generated through the breakdown of certain molecules by exposure to light or heat. Singlet oxygen is extremely reactive and has a relatively short lifespan, typically on the order of microseconds.

   Due to its reactivity, singlet oxygen plays a significant role in several important biological processes and chemical reactions. It is involved in photosynthesis, as it can be produced during the light-dependent reactions and participate in the synthesis of ATP. Additionally, singlet oxygen can cause oxidative damage to biomolecules, including lipids, proteins, and DNA, by initiating a variety of chemical reactions.

   In medical applications, singlet oxygen is sometimes utilized as a therapeutic agent for targeted destruction of cancerous cells through a process called photodynamic therapy. It can be generated by combining a photosensitizing drug and light of a specific wavelength, which leads to the production of singlet oxygen that selectively destroys tumor cells.

   In summary, singlet oxygen is a highly reactive and excited form of molecular oxygen that plays significant roles in various biological and chemical processes.

Etymology of SINGLET OXYGEN

The term "singlet oxygen" is derived from the combination of two words: "singlet" and "oxygen".

The word "singlet" refers to an electronic state in quantum mechanics, which describes a quantum system having paired electrons with opposite spins. Singlet states have a total electron spin of zero. In molecular oxygen (O2), the usual ground state is a triplet state with two unpaired electrons, which means it has a total electron spin of one. However, singlet oxygen refers to a specific electronically excited state of molecular oxygen, achieved by the promotion of one of the electrons to a higher energy level. This excited state has a total electron spin of zero in molecular oxygen, hence the name "singlet" oxygen.

The second part, "oxygen", refers to the element itself. Oxygen is a chemical element with the symbol "O" and atomic number 8.
