The HDO/H2O ratio in gas in the inner regions of a low-mass protostar
astrochemistry — stars formation — protoplanetary disks —ISM
2010/11/15
The HDO/H2O abundance ratio is thought to be a key diagnostic on the evolution of water during the star- and planet-formation process and thus on its origin on Earth. We here present millimeter-wavele...
In this paper we analyze distributions of water vapour isotopologues in the troposphere using infrared spectra recorded by the Infrared Atmospheric Sounding Interferometer (IASI), which operates onboa...
Any theory of water vapor in the tropical tropopause layer (TTL) must explain both the abundance and isotopic composition of water there. In previous papers, we presented a model of the TTL that simul...
Ground-based remote sensing of HDO/H2O ratio profiles: introduction and validation of an innovative retrieval approach
Ground-based remote sensing HDO/H2O ratio profiles innovative retrieval approach
2009/1/16
We propose an innovative approach for analysing ground-based FTIR spectra which allows us to detect variabilities of lower and middle/upper tropospheric HDO/H2O ratios. We show that the proposed meth...

本文主要介绍在4000—400cm~(-1)范围内用天然水、99.886 mol.％重水配制的不同浓度的H_2O-HDO—D_2O混合物体系,含氘10.0％(原子分数)的H_2O—HTO-T_2O混合物体系及含氘41.2％(原子分数)的D_2O-DTO-T_2O混合物体系;研究了液态H_2O、HDO、D_2O、HTO、DTO和T_2O的红外吸收光谱,并用经验规律计算了氘水的红外吸收峰的波数值。由实...
HDO measurements with MIPAS
HDO MIPAS
2008/12/10
We have used high spectral resolution spectroscopic measurements from the MIPAS instrument on the Envisat satellite to simultaneously retrieve vertical profiles of H2O and HDO in the stratosphere and ...
Absorption of Infrared Radiation by D2O and HDO Mixed with Montmorillonite
Absorption Deuterium Infrared Molar absorptivity Montmorillonite Water
2012/2/8
The frequency, ν, for O-D stretching in D2O films between the superimposed layers of different micas and montmorillonites was measured at several film thicknesses and temperatures of 2° and 25°C by in...
