31. Sulfuric acid may be written as; this is the molecule observed in the gas phase . 32. He is also known for electron capture dissociation, a method of fragmenting gas phase ions. 33. Hence the diberyllium molecule exists ( and has been observed in the gas phase ). 34. A similar concept applies to liquid gas phase changes. 35. It is only found as a dilute gas phase . 36. Combustion of a liquid fuel in an oxidizing atmosphere actually happens in the gas phase . 37. As stated above, specific volume varies noticeably with changes in temperature while the gas phase . 38. In the gas phase , this process is called photoionization. 39. A gas phase electron diffraction study confirms this data. 40. He is a physical chemist, specializing in spectroscopy of small molecules in the gas phase .
