Bhautik rasayan

Bhautik rasayan (Physical chemistry) , Bhautik vigyan (Physics) ke kaam me laae ke chemical system ke study kare hae. Ii study ke macroscopic, atomic, subatomic aur particle level pe karaa jaae hae.

 History 

"Bhautik rasayan" term ke  Mikhail Lomonosov 1752 me banais rahaa, jab uu ek  lecture course "A Course in True Physical Chemistry"  ke Petersburg University ke students ke present karis rahaa. Ii lecture ke suruu me uu ii definition de hae: "Bhautik rasayan (Physical chemistry) uu vigyan hae jiske samjhaae ke parrii,   physical experiment kae ke, complex bodies me chemical operations se kon chij hoe hae, ke kaaran.

Aadhmik bhautik rasayan, 1860s se 1880s talak suruu bhais rahaa jab chemical thermodynamics, electrolytes in solutions, chemical kinetics duusra vishay pe kaam karaa gais rahaa. Ek milestone rahaa jab 1876 me Josiah Willard Gibbs aapan paper, On the Equilibrium of Heterogeneous Substances ke chhaapis rahaa.  Ii paper bhautik rasayan ke dher khaas chij ke introduce karis rahaa, jaise Gibbs energy, chemical potentials, aur Gibbs' phase rule.Josiah Willard Gibbs, 1876, "On the Equilibrium of Heterogeneous Substances", Transactions of the Connecticut Academy of Sciences

Pahila vigyanik journal, jon  bhautik rasayan ke uppar rahaa ek German journal, Zeitschrift für Physikalische Chemie rahaa, jiske 1887 me Wilhelm Ostwald aur Jacobus Henricus van 't Hoff suruu kare rahin. Svante August Arrhenius ke saathe, ii log  late 19th century aur early 20th century ke khaas log rahin,  bhautik rasayan me. Ii tiino ke 1901 aur 1909 ke biich me   Nobel Prize in Chemistry dewa gais rahaa.

Iske baad ke dassak (decades) ke pragati (progress) me rahaa chemical systems me statistical mechanics ke application aur  colloids aur surface chemistry me kaam, jahaan Irving Langmuir dher yogdaan diis rahaa. Ek aur khaas kadam rahaa  quantum mechanics ke  quantum chemistry me develop hona, 1930s se, jahaan Linus Pauling ek san se aage ke naam rahaa.  Theoretical pragati experimental methods ke saathe barrhaa hae, jahaan pe dher rakam ke  spectroscopy, jaise infrared spectroscopy, microwave spectroscopy, electron paramagnetic resonance aur nuclear magnetic resonance spectroscopy, 20th century ke sab se khaas pragrati rahaa.

Bhautik rasayan ke aur pragrati ke kaaran  nuclear chemistry rahaa, khaas kar ke  isotope separation me ( World War II ke time aur usse pahile),  astrochemistry me abhi jaldi ke discovery,
